Noob question - is there any power bump with this mod or is it all sound (and some weight reduction).?
I don't think anyone has dyno'd to be able to tell but a guy I know that does some extensive tuning work and he figured you probably pick up 6whp or so with the cat delete, obviously the mufflers doesn't do anything performance wise but the mufflers and cats weigh 55lbs = 5.5hp, all said and done probably 11-13 whp give or take.
Thanks guys. Brian did great work and for some reason mine doesn't sound as raspy as other clips I've seen online, not sure how that is possible but it seems to be the case.
