I realize that Mufflex has a bypass system to replace the cats, but was wondering if anyone else has developed a similar system. $250 seems a little steep, but for Stainless, maybe not.
Does the Mufflex system have front O2 sensors already installed. Will need to run O2 simulators for the rears.
On my LS1, one front O2 sensors is on the exhaust manifold, the other is on the cat.
Any suggestions are appreciated.
