catback exhaust question?

[headpunter]

that is the v6 you are correct

[fierodeletre]

maybe the LS has a single exhaust and what we're looking at there is the LT?

That could be, but we've yet to see a LS yet I guess. And I thought even the LS was going to have the same engine, trans, and dual exhausts just missing like the steel vs aluminum wheels, fog lamps, ambient lighting, power seats, but who knows you could be right.

Speedy1975,
In answering your question, Sound is a personal thing. I always like the sound of Flow Masters on Muscle cars of the 60's and 70's. With those cars you got alot of interior resonance though. SLP had a great exhaust system on the production SS Camaro's like the one on my 1997 SS. It is very hard to get a deep agressive sound outside the car without getting resonance inside the car. I would like to hear a GMMG system inside the car to see how loud it is at Freeway speeds. I think Stainless Works out of Ohio built those systems for Matt but I am not sure. If you go to Corsa Peformance web sight you can hear one of there exhausts on a Camaro inside the car at cruise and out side the car when they wale on it. The Corvette people love Corsa for that reason. "Quiet inside and agressive outside." Once again sound is a personal thing that is why we have so many aftermarket exhaust companies. Jeff

I dunno, it seems that'd be pretty expensive to setup two different configs like that. I guess we'll see.

Yeah me too. I think it'd be much easier just to offer one exhaust set up especially if they are definitely going standard on the two of three models.

I just think that the picture of the cat-back on the accessory poster was just an example (which is what they actually already said) and it's confusing us because it is a single pipe vs the dual or X pipe set-up.

But it's not going to look like what was pictured...

[fierodeletre]

Not to mention the fact that they'd have to make a new rear fascia to accomodate the single exhaust, well I guess it could just be a dual out. Yeah, makes more sense to make one exhaust plan for the engine. I just think it's awesome that GM put so much performance-oriented stuff like this in the base model engine.

So, back to the somewhat original question, if it IS true dual like it probably is, the only thing really that's going to give you more performance is headers, high-flow cats and muffs, and maybe larger tubing? Maybe the tubing is already at the optimum? I have to say, at 300 + hp, this NA 3.6 has to be fairly 'tuned' from the factory. What else could we conceivably do to wring out a little bit more? If I could reach 340 bhp, I would be more than satisfied. Hell, I'm already satisfied.

Hey what if you tune your DI V6 to use premium, how many horses you would get

Ask the Cadillac guys. The new CTS has the DI 3.6.

[fierodeletre]

I doubt you'd get much if any man. That's the whole point of DI. You can run compression ratio and timing on regular gas that in a port injected engine would blow holes in your pistons. premium doesn't have any more energy in it, it just flashes at a higher temp and pressure.

[headpunter]

you are actually told not to run premium in the engine for some engineering reason. premium would not give any gains since it would not help the timing any.

[Mblock66]

EXACTLY...finally someone understands! There isn't going to be much tuning room on the FI V6. Cars come well rounded from the factory for performance, economy, smoothness, and other things. By tuning you are telling the program to care less about economy and smoothness and optimize performance.

So all cars will gain something from tuning purely based upon this theory. Going from 87 to 91 or 93 will get you maybe another 5-7hp

I would say a tuned only stock V6 will get 15-20 bhp which will equate to about 10-15 at the wheels. This is my best guess. But this is the case with most cars. The more "luxury" or "economy" the car is from the factory, the more gains can usually be seen by tweaking up timing and AFR

Guys...the pic of the cat Back is not the real one for the V6.

See JohnnyCamaro's post on page 1 of this thread and also below.

All versions of the car - V6 and V8 will have true duals with an H pipe. The V89 tips will be larger than the V6. If you order the GMPP catback, it will be dual.

The board images you see were made up for internal reviews for people who did not have an understanding of what a catback exhaust was. The Camaro "catback" will actually be mufflers and tips available for V6 and V8 applications. We will also have an "Off-Road" version for those who want to have a unique sound while off-roading your Camaro.

Yeah. I'm hoping for at least 340. But I'm hoping I can get somewhere between 350-370 @ the crank and I'd be even happier!

That's really hard to answer seeing that we really don't know what's going to be coming out for the V6 Camaro besides from what seems to be the minor bolt-ons like the CAI, and cat-back.

But in addition to freeing up some airflow with the CAI, cat-back, high flow cat, X-pipe, long tubes, & headers, tuning will be very important. In order to get the max potential out of the parts listed they're going to really need to be tuned when they are equipped altogether. Good thing is that GM is pretty good about giving codes, and there's some good software out there by like HP tuners that would really help give some additional support. But tuning yourself with say some software that hooks up through the OBD, can be dangerous if you don't know what you are doing. So take it somewhere and pay the $$ to get it tuned by professional or by someone that you know that knows what they are doing. That will also help.

Problem with NA 6cyls is that you're really not going to get any more gains unless you really work with the internals, or convert to F.I.

I'm sure they will be offering cams for the V6, but expect to pay $900-over $1k for them. And then that's going to require pulling the engine out disassembling, etc.

And a complete turbo kit, or S/C kit could cost thousands. Which is why MBlock66 is stressing that you could spend thousands to get the V6 up to the V8 hp-wise, but in the end it probably would have been worth it just to get an SS.

Personally all I know is that I'm going to be modding mine over the course of owning my car. Might take 2-3 years for me to get all that I want done to it. And I'm probably only going to spend up till about 3k and then I'm done after that. We'll see though.

To get a good idea though look at parts and what owners do to the 350Z and the E46 BMW M3. Although the M3 is an inline 6 and not a V6 and I believe that's got about 30hp more than the V6 Camaro.

That's all I can really tell you. I don't really know much more than that. I'm more familiar with 4cyl's to tell you the truth...
