Does removing the rear resonator and replacing with straight pipe increase hp?
Also is there any sensor in the resonator (sorry for the newb question there)
what benefits other than sound? sorry for being so dense here people but yeah lol

Im really looking to get more power/effiency when not in ...

so, if I do my ecu upgrade I should probably do a blow off just to be safe too. was plannning on doing something with exhaust ( just straight pipe from back?) IDk don't wanna spend 900$ i don'e have but want to upgrade now LOL like us all.
Ne way I should start a new question what mods to do before ...
