@@docsmallblock6584 the crackly came from them have tailpipes with cherry bombs. Under car turndowns just make everything rumbly sounding. (inside and outside)
Ah ,the sweet sound of my youth!. My first car was a 69' Roadrunner with a 440 c.i.d six- pak and glass packs. Drove it till all my points on my license were GONE!. 😂
lol. My first car was a '69 Chevelle SS. My exhaust went from Blackjack headers straight into 24" - 30" long cherry bombs, then into 24" long bologna cut straight pipes. They stopped somewhere underneath the rear seats. You could see the exhaust easily from a distance. I lost count of the times that I got stopped by county and state cops for that exhaust, so many times that I could quote the rules back to them before they had a chance to explain why they'd stopped me. I never once got a ticket, and we usually spent a few minutes talking about cars and engines, etc. Those were the good ol' days. We did all of our racing outside of city limits, mostly on paved country roads where there was rarely any traffic, and we always had people on both ends to keep watch. There were a couple times that we ended up being chased by cops, but even those times, when we finally let them catch up, we didn't get tickets. We did get a few really serious finger wagging and angry fusses from them, but they always let us go. Those days a loooooong gone now, but I'll always cherish them.
Had a 71 Riviera with the Rocket 455 . My dad helped me put a Erson TQ20 cam and hydro. Lifters in. Tuned it, couldn't get headers that fit a Riviera, so a muffler shop made me custom 3" exhaust with glass packs, that thing sounded rad. Funny thing , when I backed in a parking spot that bordered grass , It would pound down two circles in the grass as if you sat two 5 gallon paint cans there. Much compression I suppose. Gas was . 85 ¢ a gallon, back tires were..... @ $1. 50 per 100 miles . Lucky to get 5,000 miles out of my back tires. Damn,,, good times.
The glasspacks have a monotonous low tone, almost a dull thud, like hitting lead with a hammer. I find the sound boring. Flowmasters(and black widows too) have a lot more tones going on, closer to the sound one might imagine if demons were tearing their way out of hell. Rather pleasant.
No disagreement, but I will say back in '75, driving my '66 Nova a guy passed me in a Duster w/SB 340 Mopar, and his glass packs sounded as close to perfect as I've heard (obviously as I still remember it to this day).
Every muffer I've ever had to do got a thrush. It started about 20 years ago with a barn find new in box. My Avalanche 2500, with the 8.1L is sporting duel welded thrush currently.
My first car in 1963 was a 55 ford 2 door coup first thing i did was get a set of Glasspacks and the second thing was adding a Hurst 3 speed floor mounted stick shifter. and when I rev it it up in second gear and back it down the sound was unbelievable. I still can hear it today. Love It!!!
🟥 I had Blap Blaps (cherry bombs) on my camino. 350,Holley,Highrise,Headers,Cam,3:73 posi. I switched to turbo mufflers and it felt like I added an extra engine. Blap Blaps sound cool, except on a long, 100 plus mile journey.
Thrush were the best. At a certain rpm you could idle around the college parking lot and the windows would buzz and tic off our automotive teacher. Love them and 30" glasspacks....metallic blue color.
I had a 93 dodge with the 360 magnum and put the 32" thrush glasspacks on with no cats and true duals it and it was the best sounding pickup in my town.
The glass packs are the sound of my youth! I was 16 in 1975, so I grew up in the muscle car era. Everybody ditched mufflers and put glass packs on their cars. It was a great time to be alive!
Those are "much" quieter Glasspacks than I remember from the 70s I went through like Thrush, Bushwacker, Big Daddy and Super Muff from Doug Thorley Headers !! 😎
Exactly right. Glasspacks are basically a straight pipe with a surrounding in fiberglass. That's where the unwanted frequencies are, so the cancelation of certain sound waves if you will only leave the best sounds to the ear
Had a 65 step side 302 three on the tree six cylinder rear end with straight pipes and glass packs ... 2nd gear idling down hill on main St to the Piggly wiggly parking lot on a Friday night... Yeah... The great things when you're 15 years old lol 😂
My first car back in 1988... I got a hand-me-down 1965 Dart GT that went through both older brothers and a grandma! It had the 273cu Comando with 727 Torqueflite and my dad had installed dual glass packs that dumped right before the rear tires. May not have been the prettiest muscle car, but it was so fun to drive and sounded fantastic!
I’m not usually a glass pack but those sound nice. I totally agree on the flow masters though, it sounded kinda cheap actually. Sounded ok idling, but really bad when they reved it
It's got a cop motor. A 440 cubic inch plant. It's got cop tires, cop shocks, cop suspension. It's a model made before catalytic converters, so it'll run good on regular gas.
@@jeffreycarleton1535 the Caddy? Where's the Caddy? The Blues Mobile? I traded it. You traded The Blues Mobile for this? No! For a microphone. A microphone? Okay, I can see that. What the hell is this? This was a bargain. I picked it up at the Mount Prospect County Police auction last spring. It's an old Mount Prospect police car. They were practically giving em away.
had glasspacks on my 71 GTX 440, I would downshift under the train trestle to let my Mom know I was quarter mile from home! Mine did go past the rear bumper tho.
@@KurtfromLaQuintaVery true. Loud exhausts are a novelty at first but eventually gets very annoying, especially with the drone on longer trips. A full exhaust, crossover pipe, and resonators makes for a more enjoyable ride and still retains the mean growl on hard acceleration when combined with turbo style performance mufflers.
The 44's sounded nice, I said "yea, I could live with that". The glasspacks made me smile and I said "oh hell yeah, that is how it should sound". Nice car by the way
Love the sound of glass packs! Was never really a big fan of Flow Master’s. They do sound good on some cars. I have glass packs on my ‘70 Buick GS 455. I love the sound of the snap and pop when down shifting.
ABSOLUTELY BEAUTIFUL RIDE!! 👍♥️♥️♥️ I Miss My 69' Bird 😢💔🥀 I was told a Very Interesting story once and it was by Two Different people, same Story, They Told me Never Mess with the Exhaust from a MOPAR Muscle Car...They had the best flow and Performance than anything after market!! One guy was an Engine Builder, and both were former early to mid 1960's Drag Racers!! 👍💯♥️♥️♥️
@@danmyers9372 It seems my post was deleted by You Tube. Are you referring to my stroker I called a "Torque Monster"? I assure you with Indy ported aluminum heads... they aren't small block heads. And it was dyno'd at almost 650 ft. lbs. of torque. What are you running?
Walker used to make a muffler called the Royal Scot, it basically sounded like you are talking about. I had some on my 70 Plymouth Fury 1 440 police pursuit package car. For a while, then I put Cherry Bombs on it. I worked at an auto parts store so I got stuff at store cost. The Royal Scot was really popular in places like Maryland back in the late 70s, because you couldn't have a muffler that you could just run a pipe or broom stick thru. The Scot had a thing that looked like 6 or 8 blade propeller welded in there to spin the exhaust into the glass pack and quiet it down a bit at idle and easy acceleration.
A good friend of mine had Arvin glass packs on a very stout 350. This thing was wild. 14 to 1 compression Vinolia pistons and a very radical cam. Those mufflers were the best sounding exhaust I’ve ever heard.
Hedman headers right into 4" purple hornies on my 73 dart sport 340 4bbl, cutoff under the seat, pointing to the ground, so sound vibrated back into your seat. That was the day!
Glasspack :) Die flowmaster machen den Sound erstaunlich stumpf, aber ich denke das dem Klang lange endrohre gerade aus dem heck gut tun würde. Die turndowns am Schalldämpfer nehmen die Tonspitzen und am unterboden können auch Resonanzen gefangen werden. Der Glasspack funktioniert mit den Turndowns super, aber de ist auch grader Durchfluss und kein kammersystem Glasspack wird der tüv nich geil finden, aber ich schon
My brother bought new glass packs for his ‘58 Ford Police Interceptor Special with the Thunderbird engine. After driving it out on the highway and getting the mufflers really hot he ran the garden into the mufflers to break the fiberglass. Afterwards he revved the engine to blow out all of the fiberglass. His old Ford was pretty loud as I remember!🤗 If the cops pulled him over he could show them that his mufflers were new and still had the paint on them. Yes sir. Those were the good old days!🤗
My maternal grandfather, upon retiring from McDonnell Douglas, paid cash for an ordered 1979 Ford puckup with a 460 c.i., with a 750 Holley 4 barrel, and glass packs. I don't remember other specs, but he forgot to order it with a posilocker. Yep, it was only one leg kicking. But man, it had a nice top end. Funny thing was he would sometimes come during the winter to pick me up from school. He would rattle those cheap windows in our little school buildings. They hated him. Kids loved him. He left a few of them enough to earn some respect. It was tryuly a piece that could have been turned into a true drag sleeper.
Wow gotta say I was really impressed with the flowmasters. It had a louder, meaner sound. Like people are saying back in the mid 70s(when I was in high school) cherry bombs & thrush were all the rage.
I’ve put Cherry Bombs on countless vehicles. From a 1.5L 1983 Honda Civic station wagon to a 1995 Ford F150 300ci I6. They always sound spectacular, and I’m never disappointed. Best ‘muffler’ ever. Also cheap to buy and replace. Fantastic product.
I was 12 y/o in ‘68. I’m from Detroit. We had it all in my neighborhood(Cadillac Heights). Every make, every model, every displacement. Them white boys in Hamtramck were sick with it too. I remember in ‘70, there was a menacing Boss 302(in Grabber Blue), he had glass packs, a removed rev limiter, and he would terrorize the neighborhood. We loved him!
Many years ago I had headers/glasspacks on my '86 Chevy pickup w/305 small-block, and I miss it a lot. Very satisfying experience, and always rewarding when I'd blip the throttle and set off the alarm on my neighbor's BMW on my way to work every morning.
I had Magna Flows on my 68 Roadrunner 440. I had it past the axle just like this one, except I had dumps after the headers. It was smooth and quiet until I put my foot in it. It was great at the drive-in movies.
Flowmaster makes some great quality products, problem is, they sound asthmatic and they are like assholes, everyone's got a one (or a pair in this case ;) ).Once those glasspacks bake out for a while, the sound only gets better and you won't sound like every other muscle car on the road.
I used glass packs back in the day. They sound even better with tailpipes. They do sound better with time after the packing deteriorates. As a teen I sprayed water in the tailpipes to accelerate that decay. Fire it up immediately afterward though.
Thanks for proving glasspacks are always the way to go on a v8! I switched from flowmaster to dynomax glasspacks years ago on my 454 in by 81 squarebody 3in duals off headers and I'll never go back to a flow or any other muffler ever again! Glasspacks all day and twice on sunday!
Both are aggressive, and sound great with a V8, but glasspacks change over time as the fiberglass inside deteriorates, while Super 44's are chambered and have no "filling", so are much more consistent.
Glass Pack Hands downs! That's a real sound, not that junk from some flowmokey. I hate the sound of those flowmaster, just sounds like pure ass. just saying, my opinion.
Glass packs sound great when your foot is mashing the pedal but the idle sounds like a tractor. Flowmaster has much better idle sounds. Just my personal opinion 👍. Your miles may vary
Both of the Exhausts sound great! The Flowmaster’s perfect for grumbly idles, and Glasspacks sound far more aggressive when you push the car. I’d go for either one. Great video!
I had GP's on a car for a while and eventually got sick of the din. I switched to turbomufllers and never regretted it. Whatever floats your boat, though. I did have a Ducati that had a valve that would kick over once the motor hit around 3,000 RPM. That was nice because it still sounded nice when running at low RPM, but once I opened it up all hell broke loose.
Nope. The flowmasters sound more throaty on the car, but it's the engine in that car that makes the glasspacks sound good on it, and better fits the type of car it is.
That was great the 1st ones sounded the best p.s. In 1970 my 1969 Roadrunner 383 4 speed I put on Cherry Bombs the best sound .p.s. The neighbors and my girlfriend always knew when I was coming or going this is my blast from the past 😂
All in for the Glasspacks!! They were great in the 70'd and 80, and still are today. Classic muscle car sound!! Especially when coming back down through the gears and you get that rattle and pop!
My son and I looked into this for a Ram 1500 with a 5.7 hemi. Wanted it loud like glass packs but didn’t want to hear it 100% of the time. The solution? Cherry Bomb makes a muffler called a Vortex. It is built like a Flowmaster externally but is a straight through muffler like a glass pack. The tube going through the muffler is perforated and is surrounded by a packing like fiberglass. There is a small narrow diverter plate in it that diverts exhaust gas into the packing when running at low speeds and idle. When you stand on it the packing area pressurizes and creates a straight through glass pack sound that is only two DB back of a cherry bomb glass pack. When you are putting around town or just idling you have sound that is as quiet as stock. It gets loud on cold start ups but just as soon as the engine starts to idle down it gets quiet again. Not a super expensive muffler either. They make it in straight and offset, as well as an X-pipe muffler.
I USED 12 INCH REVERSIBLE CHERRY BOMBS ON MY 350 CHEVY ; OF COURSE I TURNED THEM SO THE "HOLES" WERE FACING TO THE REAR , BASICALLY MAKING THEM "STRAIGHT PIPES ; I LOVE THE SOUND , " WHEN THE LAKE PIPES ROAR "
I put glass packs on my '53 flat head Ford. A few ounces of oil in the carb, run it for 5 minutes. The engine sounded like it was ready for NASCAR. The sound was glorious, heads would snap around every time I let off the gas. Loved them.
Glass packs have a loud booming exhaust sound around 45mph that make talking difficult to say the least. My daily driver was a 1970 340 Duster 4 speed with 3:91 gears, a single plane aluminum intake that the heads and intake were port matched to improve flow and a set of headers. The motor would to pull a little over 7000 rpms in 4th gear as it could really breathe with this combo, there was even a very noticeable difference in low speed acceleration without having to crack the secondaries. But the constant noise was too much even for a 20 year old at one point. So I bought a pair of Flowmasters and there was no difference in performance below 5500rpm and by 6000rpm it was like I had put a pair of rolled up gym socks in each collector as the motor would not get to 6000rpm because of the restriction caused by the Flowmasters, it was quieter as an everyday car but the rpm killing construction of the Flowmasters made their staying on that car not possible and I went back to the glass packs.
My first car was a 66 Dodge Coronet 440, two door hardtop. The first thing that went on the car was dual exhaust with glass packs. Nothing sounds as good as the old school glass packs. Every V8 powered vehicle I've owned immediately got true dual exhaust as quickly as possible. I love that sound, to me, it says America. 🇺🇸
Back in my day ( 60s & 70s ) we used to pick our new cars up at the dealership and head straight to the tire store to have Kreger mags with red line tires or baby moon hubcaps with beauty rings put on. After that, the next stop was the muffler shop where we had a set of cherry bomb glass packs installed then we would go home and get ready to cruise and street race that night. It's too bad people today don't know how to handle horse power, they only think they do until they crash 😢
I have a 1980 El Camino with a 1970 mild-build 307, Saginaw 4-spd, Hurst shifter (what else is there, lol), stock manifolds, dual 2 1/4" exhaust, and dual pipes with an "H" behind the 4-spd ending with Thrush Turbos in front of the rear axles dumping on the ground. I get more compliments on the sound every time I go to a meet/show with it than I can shake a stick-shift at. Hoping to "upgrade" the Turbos to Glasspacks this summer if I can. (Limited funds/mobility from a recent hospital stint.) Been a long time since I had those and really looking forward to that extra bark. I've owned it for 21 years this year and do what I can on limited budge like so many of us do. I sure did like the Flowmasters on this car but the GPs won the day for me.
I prefer the Flo-Masters! What makes it sound even better is the over axle pipes and proper exhaust tips. Brings the sound out where it belongs. Flo-Masters get nice and mellow then!! It's the extra pipe for sure!!
I installed glass packs on the 1970 Buick GS 350 that I bought in 1978, just to improve fuel economy . That along with one of the first electronic ignition solutions to replace points got me two extra miles per gallon (12 avg mpg total) and the glass packs installed to replace the standard exhaust was perfect for family drives. Not too loud unless I wanted to have fun!
