New Mufflers - Borla Pro XS 

The Borla Pro XS is my favorite muffler. It leans towards being mild and noticeable and that's what I like. Honestly it's close to stock, it just raises the db a bit with a deeper and bolder sound. Plus its has that clean smooth sound that muscle cars should have. I can't stand when muscle cars have that raspy sound to their exhaust. Now if your like most folks who ruin their exhaust sound because they think loud is the way too go. In that case the Borla S-Type and definitely Borla Ataks is for you. But I prefer quality sound over loudness, besides I'm not a look at me attention seeking guy, especially from the cops.

Love the borla's, have them on my 70 chevelle 396 👍

I had the borla pro xs on my ls Swapped 5.3. Sounded smooth, not too aggressive as it was just a stock motor. Highly recommend

That sounds great!

While Hooker advertising budget is passed on to you w/sales, Borla prefers the put R&D into their products. Like using the 300 series stainless w/nickel in the alloy. They design products that some are looking for, but also make products using flow bench research by David Vizard who started that in 1965 and pressure sensor research to find the pressure wave location and activity in the exhaust and mufflers. David has 750+ page books on the subjects but also recommends Borla over Walker, Flow Master! The engine can produce the same open collector HP using an expansion chamber design at 2.2 CFM times liter divided by number of mufflers (1 or 2) but controlling the pressure wave, making the same HP as open header/collector race car engine yet can still reduce noise to street legal levels. He has a RU-vid channel and discusses the issues in headers, crankshaft and muffler plus more. Mechanical music, he calls it. DK, ASE master tech since 78.

Sounds good I got some borla mufflers haven’t installed yet thanks

The aero chamber’s are straight thru to they just side step a little and have a lot of packing.I have both the 2.5” & 3” although I haven’t heard the 3” yet but I always liked the 2.5’s and I never came across anyone else who didn’t but I have to say I kinda like the borla’s and I think there’s only a couple bucks difference but the borla’s as you said are lighter and made out of SS so will last longer but I just paint the hookers and let the paint both cure then bake at low temp and low care afterwards.which is better,,,I like em both but I would have liked to hear them on the road but hey enjoy em and thanks.

Nice Chevelle. I have 69 Camaro Big block 630hp. I tried the Borla pro xs 3'' mufflers. At idle they sounded good. Once I got on the car they were very loud and slightly raspy. I switched them out for Hooker Max flow 3''. The sound is deeper (larger case) then the Borla, not quite as raspy but, still very loud when you get on it. I've tried Dynomax Ultra flows and Pypes race pro and yes Flow master FX. All have that raspy glass pack sound when you get on it. Pypes being the worse. When I have the car idling you can see fiberglass particles blowing out of all of them. As far as I'm concerned they all sound like oversized glasspacks. Not a fan. I like the sound of chamber mufflers or, turbo mufflers the best..but I get the whole HP loss thing. Driving around town, cruises nights, car shows, stop sign to stop sign,.. I doubt you're going to feel a major Hp loss difference. At the track a different story.

The Borlas sound just like my Dynomax Ultraflow Welded mufflers.

Sounds nice, love the channel, I'm leaning towards pypes violaters.

Aero chamber is nothing like a Flowmaster. Far better. But still has some pinch inside.

Something nobody mentions about the borla pro xs. I put the 19" case 1 into 2 on my truck and it seemed almost as loud as the super 44 it replaced. I was disappointed because I wanted to quiet my truck down a little. It got much quieter the 1st 50 miles or so. That's the 1st time I've ever seen a muffler get quieter as it broke in. I assume maybe the stainless packing is wrapped in something to make it easier to pack and takes time to burn off.. idk... That's my theory anyway🤷‍♂️

The Borlas.

Quieter on idle but with throttle it's time for Mr Raspberries 🙂.. way, WAY sicker😍

The Aerochamber is my fav V8 muffler. I had them on my 86 Cutlass and Nissan Titan. Best all around sound and performance. I currently have a ProXS on my Sierra with LTs and no cats. It's an amazingly quiet muffler. Dunno how the hell Borla does it with it being wide ass open as they are, but they do. If Hooker still made the 3" in/dual 2.5" out, I'd have an Aerochamber on my truck, but ProXS it is now lol.

From what I've heard the Hooker Maximum Flow are much less restrictive.

They do sound different , depends on what you prefer . I kinda like them both, if that makes any sense . lol. I just put Dynomax on mine and will make a video . Do you not like the SS exhaust tips ?

heres my 509 with full 3 inch x pipe dynomax 17665. sounds louder on camera . quiet in person

Sounds good! I’ll hear it in person soon. Sounds a bit quieter than the hooker.

I'm thinking about switching from flowmaster 40 to Borla

Sounds good 👍 I'm using flow masters 44 series

Was there anything in particular about the Hooker Aerochambers you didn’t like? I’m running Borla ProXS, just wondering sound wise how they compare. So hard to tell with videos, they sound similar.

Are crate mufflers universal? Are they something I can just get welded on to my scat pack or hellcat?

I think the hooker mufflers sound better

How about 6 cylinder motor for 2010 jeep

According to engine power the hooker make more power than all the major brands tested in that episode which Borlas were included in that test.

I am soon to put new (dual) exhaust on 73 Dart sport, 2.5 pipe, with 340 engine. People- advise me on a "loud muffler" Without big drone inside. I've heard Flowmaster delta flow 50, I like sound outside, and I can live with drone inside, but would like a little less drone. Suggestions?? I'm not a racer, I just like the sound......

Hooker mufflers sounds way better

Flow Master 2 chambers can’t be beat.
