I'm having a twin silenced exhaust system made up, 2.5 in all the way through but i've bee wondering, does it matter what size the tip of the rear can is ???
I was thinking of having a nice 4 or 5 inches but will that effect the performance ?
I know from reading through thread's on here a 2.5 in system is the optimum size for an N/A but i can't remember seeing about the tips.
Anyone know or got something similar fitted ?
