im not sure which is better but a friend recommended a pipe that increases 19% power but question if u get pipe do u need to do ne engine work??

 

all depends on teh pipe what power u get, if u get a differnt filter, and if u re jet, i am getitna a bills or PC t4 pipe proflow w/KN and a stage 1 or 2 jet kit. if u get a pipe best to do is. to filter and jet it. or just rejet
