i want to get a gmpp exhaust or buy the corsa system offered by the actual chevy place. I'm not sure which to get so any info would be helpful.
also what kind of power gains should i expect from an intake and exhaust; will it be noticable. Does anyone know if the two mods affect gas mpg.

 

You should search the forums, but yeah I recommend the GMPP for very little performance, and warranty. And most people will comment on the MPG gains.

 

how do you think the gmpp compare to other exhaust systems? Any suggestions? by the way it is on a 2006 LT with a manual tranny.

 

If your looking for the most power for yer money go custom and go full not just cat-back

 

GMPP Short Ram Intake = 2 WHP
GMPP Catback = 8 WHP
You will notice the 10 extra HP but if you want to go a step further get the LSJ Exhaust manifold and Downpipe at the same time.

 

In a magazine I was reading they did a GMPP intake and a GMPP exhaust on a 2.4 and they dynoed it stock and after each mod and the WHP gain total was about 8WHP.

 

and us 2.2s can expect less....

 

Ok now i know how much power to expect, how is the gas milage affected. I've seen some people say it went up. can anyone else vouch for this.

 

Your mileage should be better than before. Mine was. That is, if you don't lay into it at every opportunity.

 

You'll be tempted to lay into it at first. Have some fun with it then reset the MPG, mines gone up 2 so far(had it since tuesday), as I've been romping quite a bit with the new gmpp intake($160 shipped! Thanks balmung)
