hi, there are some things im trying to get figured out and hoped you guys could help.

i have a 2009 cobalt LS 2.2l what intake is best for quality and price.
sam for exhaust, header, highflo cat, muffler, can, w.e set up you think is good and the brand.
finally im looking for PCM tuners also.

any help would be appreciated

 

i love the sound of the gmpp performance exhaust... kinda spendy though
zzp mid-length header/catted dp
injen cai
trifecta tune from vince...

all this stuff has been covered several times just about every other thread lol
but if you want to keep your warranty which im sure you do... dont get the tune
