I was actually thinking about full 3 inch exhaust (no cat, no resonator) with a Cherrybomb Vortex mufller. I'm assuming they have little restiction on then because they don't have any baffles

They really have a badass heavy sound on V6s or V8s. This is the setup i wanna go for next summer. Here in Montreal Canada, cops are anoying always sticking a rod in your exhaust (if it's strairght thru, 255$ ticket) even if it's not loud
I currently run a Blitz cat/back nice sound.. what makes the difference in the resonator and the cat.
resonators give it a deeper sound, cat removes alot of high frequency noise.
another must for exhaust it to use thicker pipes.. also removes high frequency noise.
.....Not bad for my first ever Nico post!!
