Aero Turbine Mufflers

SS Crew · April 26, 2005

I talked to Lyndon at Wester's Garage about some changes and he told me he has a remote location in So Cal. He gave me the number and I called them up. The guy told me of a muffler called an Aero Turbine muffler combined with an AFE intake netted 60 horsepower on an 8.1! That's right 60 hp. I find that hard to believe.

I checked out Aero-Turbine on their website and it shows a jet engine looking muffler that claims to reduce backpressure. In fact, it says it works like an expansion chamber creating a vacuum. It all sounds good, but isn't too little backpressure bad for low end? The sound clips sound kind of flatulant.

I was wondering if anyone on the boards has any experience with this muffler.

Well, actually, ALL backpressure is bad for a gas engine. What you actually want to worry about is exhaust velocity. Opening up the exhaust too fast decrease velocity, and that is bad. So, if the aero turbine muffler really does decrease backpressure while increaseing velocity(supposed vacuum effect), than it would be good. However, I have no experience with them. There was a guy on the dakota boards that had one on the 4.7l and liked the sound, and said that by the butt dyno he felt an increase.

Ive seen them before and in my opinion... there is alot I can do with 200 bucks and buying a muffler isn't one of them.

I personally would rather save my money for a bolt on supercharger.

Where can you get a supercharger for $200.00? At least one that works.

If you went and added a supercharger, you'd need a performance exhaust anyway.

I don't know about this. The dyno charts are kinda iffy. I mean the hemi chart doesn't show anything until 3500 rpm. Why's that? The 8.1 liter in gmc and chevy trucks don't make any hp or torque until they reach a little over 2000 rpm did ya'll know that. It seem this muffler solves that though. And it must suck for anybody who has that engine because at around 3950 rpm the hp and torque drops to 0. what a bummer. go ahead and get a throttle body spacer when you pick this one up, it's right up there with it. It might actually do some good at a certain rpm but with them altering the dyn o sheets and leaving out info I don't trust it. Mr. says run away, run away!

keyword, "save"...

as for needing perf. exhaust anyways... an aeroturbine isn't any more of a miracle worker than a K&N filter.. .they have their benefits but the question is.. if its worth 200 bucks per muffler for you personally.. for me its not

You said "there is alot I can do with 200 bucks and buying a muffler isn't one of them." You never said that you were strictly referring to an aeroturbine. I don't have any experience with aeroturbine, so I can't say if it's worth it or not.

Fair enough... just a play on words either way.. There was a post on www.s10forum.com awhile back.. I believe it was in the 262 CI 4.3L v-6 forum.. feel free to search for it.

Some of the people had them or new people who had them.. If my memory serves me correct, they sound great, but didn't make any noticable gains. But to be sure, go search for the posts.

EDIT:

Here are some of the links, I was bored, Im sure this post will end up the same way these did.. not really proving anything haha

heres 1

Heres the second.... Lets see who can figure out my other alias, shouldn't be hard

I talked to a couple of muffler shops about the Aero Turbine muffler, they said if I want quiet rumble this is not the muffler, it's LOUD. They suggested a muffler called Flo Pro. I think I've noticed a couple of references to that muffler. Anybody care to comment on them. Their website shows some direct replacement for the GM HDs.
