best exhaust w/o Cat swaps?
 

Asked nissan today what voids my warranty, and they said i can change my exhaust but only from after the catalytic converter. So what the best exhaust out there that doesn't mess with the original Cat? Thank you, all your knowledge is appreciative!

Did you try searching this? About every other day there's a new thread about this. Generally it's split between Fast Intentions' and Motordyne's CBE's. There's a lot of other options beyond those two also.

:iagree: This can go on for days, weeks, or months & you will never get an exact answer b/c everyone will have their own opinions.

Go to YouTube, type in 370z exhaust, make a pick.
