blackhawkxx Posted December 5, 2003 Posted December 5, 2003 How much more horsepower would there be when going from a set of slip-ons to a 4into1 full system on a jetted carbed Bird? Quote
BIG BOY Posted December 5, 2003 Posted December 5, 2003 I would say 5 - 10 more HP depending on jetting and exhaust. Quote
