Hey guys hows it going, just joined the forums. Had a question, My cobalt ss has a INJEN intake that i just put on... it has the injen filter as-well and lets just say the Supercharger is not louder at all . Any reason for that? thanks guys

 

You won't notice any difference city driving.. Go WOT.
Do a second gear pull starting at like 3k.

Come back and tell us the results.

 

still no supercharger wine, my exhaust is also very loud too its a SLP loudmouth header back so that's probably why. figured i could still hear it ill just have to buy the ZZP stage 2

 

i have zzp stage 3 and zzp headers/dp and cat back exhaust. my exhaust is since putting on the headers/dp that i can't really hear the whine anymore of s/c. i'm sure it makes a louder sound. have someone stand on side of road and do a pull by them, u'll hear the s/c in the video. or have someone else drive ur car and do a slight fly by while ur in another
