Stock 2021 red eye exhaust manifolds with catted factory down pipes 700 miles on the car .
No, these would be for a friend that was looking for some cats just to possibly pass state inspection.If you get the mid pipes I could use the flanges off yer old ones. If yer willing to chop em off n ship?
@Mean Cat
I've heard of gutting them but adding tubing is new to me, why ? sound is better ?One more reason to leave all the turns that the oem mids require, cut out the cats, gut em, put a straight piece of tubing inside, and to weld em back together and weld them back into the system
