i guess owning a worked r33 series 2 an r34 GT-R means i got no idea hey??? quick to have a go aint ya?
had a friend with a r33 gts4 n/a with exhaust, there horrible.....
n/a = ricer/wannabe
my advice, if its n/a, keep that engine muffled
they arnt good but neither are n/a rbs, i believe both are bad, but id hate to drive a tinny raspy go nowhere n/a rb with that annoying droan that they have
