SRT-4 Guys.. Need Your Help
Well I know a couple of u are members here and i posted this on the srtforums and no one wants to answer my question so maybe my fellow community SRT-4 members may be of some assistance....(this is what i posted on srtforums)
Ok, to start, my friend has a 2005 SRT-4 with Stage 2 and Turbotoys. Well, I love the way the SRT-4's sound. He still has the stock exhaust. Well my question is this... I have a 2005 Cobalt SS/SC with Stage 2 and was wondering what the SRT-4 stock exhaust consists of because I want to see if I can get something similar out of my Cobalt SS. I know there cars are totally different as far as displacement and how it's powered. I'm SC and I know the SRT-4's are obviously turbo'd. Single exhaust and the SRT-4's have single to dual out. I'm 2.0L and I believe you guys are 2.4L. Not really sure if any of that makes a difference. I was told you guys have just a resonator with no muffler stock? correct me if i'm wrong. If so I would like to know the length of the resonator or if anyone has any suggestions i'm open to idea's. Thanks for the help

I don't know how long their resonator is however you are correct. They don't have mufflers. I know that a turbo back exhaust nets like 20-25 whp alone for them. Trust me, we won't be able to gain that much through an exhaust with minor mods done to our car. We can't have turbo back exhausts, however we can have full exhaust setups such as a long tube header with downpipe, high flow cat, and exhaust. That would definately get us around 30 whp but for a costly price.

Our cars do not come with mufflers. It consists of a downpipe with a cat to a single straight pipe down the middle of the car to a "y" right underneath the backseat that branches out into the dual exhaust tips you see. The pipes actually start to turn back toward the front of the car and then bend again to head out the back, really odd. Do a google image search and you might be able to see what im talking about. The turbo muffles the sound enough to be able to do away with a muffler. The reason our cars gain so much from an exhaust swap is simply because its turbocharged. On any turbocharged engine, the bigger the exhaust, the better. Check out the exhaust systems on a diesel truck and notice the diameters-huge (like 4"). The key on the SRT seems to be either an open downpipe or a 3" turboback.
Tell your friend if he wants to make his car really wake up, and I mean really- put a 3" turboback on it. He will see atleast a 1/2 difference in the 1/4 mile ....

negative, there are two 12 inch resonators just behind the cat under the middle of the car. the sound of our exhaust is also effected by our ecu tune, if your attempting to get that popping under deceleration, then you need a EMS system to add fuel on the decel curve.

You don't tune a car to add fuel under no throttle (deaccel) situations. The noise is created by the fuel that was allready there before you let off the throttle.
Cobalts do the same thing not to mention anything else that has a decent flowing exhaust.

personally, can't see why you wanna sound like an SRT4, they have a nice growl which I like but the stock exhausts i've heard sound like crap under load and pop when not under load.
I have heard a few aftermarket ones that sound pretty badass.

I have the Maxxfabb side exit exhaust with a race cat and Stage-2, if I hit the rev limiter at night I still get flames, and it pops and burbles a ton off the gas, even in first gear going through a parking lot at 5MPH!! As for my tune I am at 12.1 with alcohol injection, so little chance of me dumping that much fuel into my exhaust, but it still lights off when I lift and snaps/crackles
