I have a 4" HKS cat back system with a 5" cannon & a fake cat and it did 99db @ 3700rpm...
It made a real bellow... near impossible to be discreet around the po po!
It's getting changed before she's back on the road..
K & N KNRR3003 (has the crome lip)
3" Inlet Pod Filter (universal Fit)
I have had it on my R32 for approx. 12 months..
Looking for $40 for it..
Located in Brisbane.
It's quicker then any r32 rack (less turns from lock to lock! ...and then i have nice light steering and a fully locked rear end!!
Yep I am using one of them!!
Nice.. let me know how the tune went and the power output!
