Good point. They did put a lot of research into the stock sound - Fourier Transform and all. With a little luck, we may just like the stock pipe's sound good enough we can all save some money. But I'd also really like to hear the LPO performance exhaust before deciding. Don't know how that's going to be possible!?!

One word of caution for those of us that have ordered the automatic transmission, wait a while before making a decision on which exhaust to put in if you are looking to do this mod. The A/T model cuts to 4 cylinders in certain situations, I had a Chrysler 300C that did the same thing. This becomes a challenge to exhaust manufacturers as when it goes into the 4 cylinder mode a slight "drone" is created, a sort of a low level hum. Stock systems take this into consideration and keeps the drone to a minimum. If you put certain systems in the low level drone becomes an unbearably loud hum when it kicks into 4 cylinder. There were several exhaust systems that were created for the 300 that addressed that issue so hopefully they will replicate it for the camaro. Some 300C owners just put in long tubes and were satisfied with the results.

Camarospike, whats up with the wiggly exhaust that makes it sound so much better? Does it ever pop open on the road?

EDIT: Ok now I get it, automatic/manual cutout. Very clever.

I think it's that crossflow that jacks everything up. If you were to install a standard single in single/dual out, that would be different, but I've just always heard this really whispy sound that was always crappy to my ear. It wasn't a good tone at all.

Regarding the AFM on the autos' making drone - I wonder if the GMPP catback will take care of that. It's stated it meets all noise requirements and such. I say go for the off-road catback instead

GM has been working on the exhaust for the L99 for quite some time now to make sure it is the best.

yeah, I've seen true dual setups with dual mufflers that sound decent, but the catback systems as a whole from flowmaster suck ass

do you think it would be too crazy to tune out afm to add a loud exhaust? i plan on doing that if it doesnt completely kill gas mileage(which i dont think it will)

well, just tuning it out will only make a difference when it would normally go to 4cyl mode as far as the sound goes.

with the AFM system in the car you have a different lifter setup and a slightly different cam grind, which.... if you dont care for afm in the car at all, you might as well swap to the hot cam and swap the lifters out as well.

Good Exhaust system for LS3 SS

Hey guys. Ordered the SS LS3 with the Hurst STS. I know this might have been mentioned before but i was wondering what a good exhaust sytem would be for the LS3. Im not too sure i want to change the stock sytem but if I do want to change it down the road I would like some ideas. Corsa, Flowmaster, Magnaflow...? any ideas?

then get the manual....



seriously tho, short of swapping the whole cat-back to an aftermarket system, you could pull the mufflers, cut the baffling out, then reinstall them.
also you would have to check with GM about removing the AFM from the car, tho if you are swapping the lifters and cam anyway, then you wont need to worry too much about your warranty.... unless you pay someone to do it.


I honestly feel that a lot of people will enjoy the sound of the 4cyl mode when cruising. then there will be some that would rather have the constant drone at highway speeds.

Maybe you could just disable it through the PCM. Leave all the hard parts alone and do it electronically, unless you're throwing a cam in there. I wonder if a dealer would do that for you...

'Energyforlife - IMVHO, your ideas on CBs are great. Congrats' on your order but also keep your eyes open on GMPP CBs. If I remember correctly, there will be two, a standard street-legal and off-road-only CB. I'm sure the prices will be similar to what is going to be out there in the aftermarket but you should be able to roll the cost into financing the car and have GMPP's warranty

Yes. Borla is not cheap. And they are somewhat loud, all the time. Tops in quality, though.

I like you resonator eliminator idea. You could have a GOOD exhaust man custum do that well, and reasonably priced.

Here's a couple of more ideas to enhance the possibilities:

The NPP Dual-Mode exhaust on the Corvette is a THRILL! It's like a straight-through shot where the two pipes with the butterfies open. I bought the mod kit, so you have remote control NPP.
You choose when the butterflies in the 2 of 4 tailpipes open.

You can set it open, even at idle.

Closed - all the time or

Regular program - opens around 3800 rpm. Roar!!!!

It roars, screams, primeval stuff, yet cruises the highway quietly.

Some vendor will be cashing in on the Camaro with this. They have kits to add to Corvettes now.

Lastly, more than a few G8 GT owners have modded their exhaust, because it is very quiet to hide the AFM unpleasing note when 4 cyls are off.

They remove the resonators and like it. But not at highway speeds, where you get the dreaded DRONE.

Some G8 GT and Challenger SRT owners have installed cutouts. They have them electrical now.

Nice and quiet --- Holy ...., wide open, just behind the cats, with a sidepipe cutout-only exit. giggle....
