Ive been told it duz but would like to hear from experience!
13hp and 4ft lbs of torque. +2hp with the Yosh Cyclone.timyates519 said:What was your final tally w/ the M4 / BMC race Mike? Before switching to the Yosh..
that was the max i saw. it was 123 stock. we did the set on a seperate day and i gained 2hp but it was not with the final pipe, filter, map combo. i'd say 13hp gain is accurate if slightly conservative.timyates519 said:And your final RWHP output though? 136?
slip on only.whiskyshooter said:Mike did you have the full exhaust or just slip on??
