Aftermarket Exhaust Question

[Johnnycheese]

Before I did any engine mods on my Gen2 I did a full exhaust... I did 4 baseline pull's at a buddys shop,rolled the bike off the dyno,let it cool for 30mins or so while taking the bodywork off,removed the stock exhaust&put a full Akrapovic on w a PC3..rolled it back on the dyno 1.5hrs later&it showed a 10hp gain w a zero map in the PC....

reread the post I said put the pipe on you will not gain if it is not mapped
didn't say you will not gain by putting the pipe on
