im looking at glass packs off the headers to a 45 deg bend the angles downward, what do ya think?

 

its gona be loud inside the car and out. at least this way if you dont like em your not out alot of cash.

 

yep,i like loud, and i have a ported in take so cai, 58mm tb, and 58mm intake seems like it would be taking enough air to "keep up" with the exhaust... i hope it wont sound to choppy or poppy...crabby, can you check out my thread about the ltcc? id appreciate it

 

yeah glasspacks to a side exhaust will be loud as hell inside. hope you don't have a girl you enjoy talking to.

i've always loved the sound of longtubes into a magnaflow catback. nice rumble and really opens up under acceleration
