MAGNAFLOW 10416 VS FLOWMASTER 40 SERIES 1969 FIREBIRD 400 

WOW, those Magnaflow really did it. Sounds as beautiful as the car looks.. I put Magnaflows on EVERYTHING I own, even my lawn mower, LOL.

Imma flow master guy, but after this vid, imma have to jump ship and be a Magnaflow guy. Those mufflers sound hella good on ya whip. I’m sold

That’s a beautiful Firebird and it sounds Amazing, I’m going with those on my cutlass . Cheers

Great sound, thank you for the video. I want to instal these on my 454 c10

1971 CJ5: wasn't sure if I was going with flowmaster or magnaflow. Your video made the decision easy....magnaflow. thanks dude 🤙

Man you’re car is gorgeous

I'm a flowmaster guy myself but flowmasters only sound best with full lengths rather than axle dumps. Still would pick the 40's over the latter though

Nice video good comparison I was going to originally go with magna flow’s but was just doing research I’ve had flow masters before but magna flow really have a clean Chris sound sounds perfect

I'm about to put a set of these Magnaflows on my Tundra and I was wondering how they'd sound on a V8. Thanks putting up this before and after. Much appreciated, and I really like that old Pontiac. We were a Pontiac family in the 60's, 70's and 80s.

The Magnaflow has a more low tone clear sound. The Flowmaster has more of a rumble, and bit higher pitched sound.

Love this car man 🙌🏽

One of my my all time favorite cars! And yeah, sounds great. Can't say I'm a fan of the matte paint, but I'm old so I like to see these cars finished as we would have done them up back in the day.

Sound really good...my first car was a 68 bird ..they are so coool..

After seeing them locally for over $100, I won one on eBay in box for $40. Really glad with my buy!

I can't help to think this thing would sound even better with some full length tailpipes....hint hint.

I might add that the magnafows sound better with some length of pipe past the muffler. 3' to 6' of 2.5 - 2.75 inch pipe will give it a deeper rumble than you have with the turn downs. That and if the exhaust exits the back of the car you won't have issues like rust or soot on your undercarriage.

How loud are these compared to the flowmasters? Magnaflows are much more my taste, sounds amazing

Great comparison, thanks for sharing. I've changed my motor combo. around and plan on changing my exhaust as well. So with that being said I don't own any MF or FM and you have me thinking hard about the MF 10416. I'm curious about your thoughts on being inside the car between the two now ??? I feel like the MF sounds better and lets the "motor" do the talking whereas the FM is a higher pitch tin can sound. In my option, some people like more noise because they have less motor.

Depends if you like the marbles in a can noise or deeper throaty sound.

Omg i was literally days away from buying flowmasters after days researching now nop definitely geting magna flow. Only downside inheard glass or wool in dagrades after few years??

i have Magnaflow 3 tum on my Firebird 1971

Hey is it stil same sound? Or louder now that is used for a while????

Did you notice any power gain doing away with the Flowmaster's or any weight saving.

Wow, those Magnaflows sound like Glasspacks!

👍magnaflow

Hows the droning when driving???

What degree you have your turndowns

Hate Flowmaster. What did you do to get the paint to look like that?

Are those the MagnaPacks? It sounded much better than the Flowmaster.

Magnaflows everyday. flows are painted steel that will rust

Hows the drone?

Sounds good but in do time the magna flow gets louder (watch)

Dude Bryan Herman. What’s up

Send more videos intersed ty.

nice MAGNAFLOW 10416 is wicked sound very nice i will buy one myself

Flows sound way better

Morevideo

the MF sound much better, i did the switch, magnaflow and dynamax straight throughs are supreme. btw you might have an pesky exhaust leak

I'm more of a Flowmaster guy. Not a fan of them straight through "mufflers"

Lousy review....cars,sounds like crap...get a tuneup lets go brandon🤡🤡🤡

Is the magnaflow 10416 same as the 14419?
