Re: Making a torque pipe
realize your talking about a 1hp difference in midrange power from two different pipes. what you should focus on is finding rpm's and perfect tune. the sbp or proma gp clamp on is a great choice till you pass 8-9000 rpm. below 4000 rpm anything has potential really but something like the mini 2stroke atv exhausts will be the best down low.
