Im thinking of getting a new exhaust made up for my R32 GTR....will a 3" bore system be sufficient or perhaps slighter larger piping? ie 3.5"

Ive got full stage 1 mods + HKS 2510s....need a few more goodies yet but i think around 500-550bhp is realistic?

thanks

80mm seems a popular size, 90mm for the race spec ones

the hks hi power silent is 95mm but only 80mm by the flange nere the cat.

 

[R.I.P.S NZ]

3 inch is OK for that amount of power (550hp) if you plan going much over that go bigger to be safe.
