ok... so with some searching i think ive came to the fact that the gm header isnt really worth it. So with more searching ive seen that the zzp header/downpipe, is a good thing to get.So does anyone have a sound clip of a zzp header and down pipe with the gm performance catback?

 

if you dont have stage 2, i would save for that. dollar per power= stage 2>header and dp...
just my two cents

 

no i dont have the stage 2 yet. but now that you put it like that maybe ill save for my stage 2. man they was right when they said the 1st time you mod your car...u wont be able to stop.
