Cutouts- Pre cats or Post Cats.
 

Hey guys, im sick of my muffler, so im trying to get my hands on a stock muffler and then get some cut outs. Should i place my dual cut outs after the cats or before the cats. which is best for sound? Performance? Thanks

After or you will be throwing codes.

I put mine after the ball-socket joint in the stock exhaust system.

AFTER or you got :turd:

so will i need a retune with the cutouts? Also what would yield better mileage in highway driving cut outs open, or stock muffler?

i put mine here... this pic makes my truck look rusted:(

if you have it open im guessin there will be a small increase in mileage. it wouldnt hurt to get it tuned for the cutouts

Yeah I got mine after the sensors. Its funny to pull up to a lite and watch the people jump when I romp on it.. hahaha.
