Best complete exhaust system...

I like the corsa, I don't have it but I like the videos. My flowmaster has a tone low enough to compare to a deisel (almost not joking). At WOT however its almost as loud as open exhaust, driving next to a wall with the windows down its defoning.
Also, I'v been watching and watching before and after videos of the GMPP exhaust and I just can't hear a noticable difference, even in the drive-by videos!

Most cat backs include one too but i just took it off cause it creates less flow and backpressure. At the MagnaFlow web site the muffler alone I think is around $240. I can't remember what i paid i got it put on as soon as i got my car.

Will the 2.4 w/ a turbo wind up being faster than a 2.0 w/ supercharger and stage kit?

i have a magnaflow 2.5" and i love it, i first thought it sounded kind of ricey but now i really love it, not sure if it still sounds ricey or if i just got used to it after it resonated. 2.5" is good for our cars. smaller diameter= better low-end torque, larger diameter= better high end hp. and with turbo cars 3" is good not as much b/c of how much hp they make but more b/c the bigger piping allows the turbos to spool faster. and the resonators are there just to tune the tone of the exhaust, nothing else, they were explained to me at my school as the same theory as blowing at the tip of a soda bottle and the tone was changed by how much liquid was in the bottle.

i have 3'' from the cat back and an apex muffler and it sounds amazing!!! its very loud and you can hear it from a couple of blocks away. kids are always turning and my neighbors hate it. i plan on getting a new cat though and running 3'' all the way. i had magnoflow and hated it it sounded way to much like a fart so i went to apexi N1 turbo

I really dont think exhaust is worth it because everything except stock sounds ricey. I like the sound of the supercharger with intake and thats all I want to hear. Maybe there'l be a good 3" that comes out, but until then...
But do you guys think that I will need a bigger exhaust with all my mods...

If I was to buy an exhaust today, I think I would go for the GMPP > It has the cleanest sound, and seems to be the better bang for the dollar, I mean really guys is there going to be that much different in gains between each? It's just like picking out a CAI, it's a pipe! The only difference is the sound on the exhaust end.

The GMPP is only 2.25" piping though. I would go with 2.5". The Grand-Am Cup Cobalt swithed from a 3" custom Corsa exhaut to a 2.5" custom Corsa. They are also running Stage 2 and then some. I would stick to the 2.5". I don't think the GM race teams would have switched if it didn't perform better.
With a turbo, you want the least amount of backpressure after the turbo as possible. This allows the turbo to spool faster resulting in more power sooner.
With a N/A or S/C engine, you want some back pressure to keep the low-mid torque. Too large will result in higher end power, but our cars only go up to 7000 rpm (without touching internals), unlike other 4 cyl. reaching 8000-9000rpm.

yea i agree with you.. every talks about want deep tone and blada blada blada.. but im sorry.. its all rice sounding with a 4 banger.. tone and deep is a bbk equal shorties with bassani x with 40 series flows w/ dumps with a 110 lobe seperation... thats exhuast.... these are all pissed off bees in a can.

The Grand Am Cobalt is affected by power restrictions also, that's my guess as to why they switched to a 2.5" exhaust.

Yes its all about flow...however you need back pressure to make a 4-cylinder car run. With us having supercharged vehicle it changes that dynamic a bit, but we still need some back pressure. Not much but some. I people would talk to the other right people you guy would go and get an exhaust made. Cat-backs are nice...but you still have an exhaust system that is screaming help me. if you dont do the whole thing you wont ever realize what your playing with. This goes for everything on this car.
