so i installed an ss/tc agency power catback on my ss/sc. This thing sounds awesome, even though it has a resonator it is louder then my non resonated 2.5" exhaust with borla muffler. In order for it to fit i had the flanges cut off, and extra piping tig welded on because the two dont match up, then i had a v-band clamo connect them. I also have a zzp header and DP.

Sounds pretty good man damn its loud though lol. Are you catted?

 

sounds better than your last set up, im liking the winter status

 

yea its very very loud, but not raspy, my last setup had no resonator and some rasp, this has a res and is louder but no rasp really in person. Yea i am catted, i used to have a 3" dp but that **** was soo loud i went to a 2.5". And steelies make out cars look like **** haha.

 

Agreed lol I'm not a fan of the steelie look
