Do you have a dyno slip saying you make that much? Not doubting you, but i see alot of folk slap on alot of bolt on and stuff and think that all the crap added togeather adds up to 400HP..lol when really its maybe 30.added HP. post up a list of what you have done. really for anything streetable with decent HP you only need 2 1/2 dual , you really want to keep the exhaust gas velocity up so it helps pull everything out of the Cyl when the exhaust valve opens up. good article to read about exhaust.
