thinking of going supersprint manifolds back for my m3
Discussion
im running a single exhaust on my e46 m3 now (bought it like that ) but thinking of going this setup:
supersprint: front pipes (decat)
centre exhaust with resonator
Rear exhaust OO 80 Right + OO 80 Left
stock manifolds for now
does anyone have this?
im worried about sound and if ill pass noise limits for track days (would be nice to get to get on those 98 days) and also would assume most the power gains are from the manifolds, other than noise/looks would you think i would get any hp gains ?
thanks
