GM exhaust
Ok, there is a GM touring exhaust system for the cobalt on ebay and the bid is at 255 right now. But i really want the performance one. should i try to bid on the touring since i might get a steal, or just save for the performance model?

dude its really about what you want your exhaust to sound like. You seem to have your mind made up you want the gmpp sport. Why is that? The dif between the 2 is the tone. The touring is more subdued.

yeah, I know, but a steal is a steal. I like the louder exhaust(my kid falls asleep!) but i could settle for the touring if i could get it for way cheaper.

The touring has a nice deep tone, you can just hear it at idle with the windows up, and just a little at crusing speed. Any louder at crusing speed and I think that it would be annoying.

Yeah, the performance is VERY similar. I've driven two cobalts with the systems, I have the perf one on my car, and its much like the stock exhaust but louder. Retains the nice clean tone of factory exhaust, but you can hear it. Mine is very managable even without a cat. Ported stock manifold helps me out as well, to lower the tone and keep it nice sounding.

from my experience, it's best to get the parts you really want, even if it means spending a little more or waiting a little longer. because in the end, you'll be kicking yourself that you didn't get the parts you want.

Eh, sounds nice on my car. Solstice is a lot different though, even the manifold is different. Things like that can have a big effect on the sound of the exhaust. I know porting my stock manifold made my car much deeper and poppier in the lower RPM range, almost cam-like at idle. People have asked me more than once what cams I have in the car.

I know you can't hear much of a difference inside the car...but outside the car is a HUGE difference.

My car would be too loud for some people, it bothers me sometimes, but it sounds sexy at WOT and low rpm cruising, and with DFCO turned off, it burbles and pops like an SRT-4 when coasting down in gear. I love it.

And it does it mainly at low rpms, not high as much. under 3K let-off in gear sounds fantastic, and since thats where I spend 95% of my driving time, I'm happy.
