Really? What about lifts?

Funny my lift, exhaust, tuner, CAI, anything have ever voided any part of my warranty other than for those parts.

Cut the rear two cats off, you still still pass emissions, notice a power improvement, and the truck will get slightly louder.

i have seen people cut them out, beat out the inside of the cat, and then reinstall them. same effect as not having any, but you cant tell without cutting it open!
