If i were to have the driver side cat relocated about a foot farther down the y pipe, would it at all affect the smog? i know it would fail any visual inspection to anyone that knows stock 4th Gen F-bodys. The reason I ask this is I plan to get electronic cut outs to dump before the cats. the passenger side is no problem. but since the driver side is basically right their at the manifold i couldn't do it the way i planned. and yes i have taken the exhaust off after the cats and it doesn't sound any louder then the pipes i have on it now so e cutouts after the cats is a no. Now if it would aftect smog, would i better off not touching a thing. or getting a off road y pipe?
