i know theres alot of variables in this question but i wanted a ballpark idea if you guys could help. im putting together a 89mm x 79mm 492cc drag port cr500.... i know it will depend who builds my pipe and how well it works with the porting but how much power increase could i expect to see from a inframe drag pipe versus a stock or FMF pipe ?
