how much HP gain w/ these mods
 

Im just wondering a ballpark range on how much HorsePower gain I will get w/ these mods

Magnaflow Cat back exhaust syster
Spyder Auto headers
a bigger throttle body

umm...2006 accord v6 right? headers?? i believed that the exhaust manifolds were welded to the block. that may not work. as for the catback youll get some, maybe like 10-15 as ive heard. as for a bigger throttle body i wouldnt really bother i dont think they make much of a difference on N/A engines. do exhaust and intake and you should notice some difference.

i doubt you will get 15hp from a exhaust, esp not to the wheels

yeah not to the wheels lol. im just guessing. i know its not much. my car tends to see power come faster than it does more power if that makes sense at all. i mean what am i even probly gaining with everyhing? lol. i have the bolt ons metioned plus ngk plugs, platinums, removed ac. never dynoed. well maybe after that manifold work and some other things:D
