I went to my mechanic today and he said he could do a custom y pipe from the rear suspension where it already is and have 2 pipes sticking out. But he said if he removes the silencer thing at the end of the exhaust (black thing) There might be a check engine light do to back pressure. Anyone experience this, or have done any kind of dual exhaust setup?

Plenty have been done on the V-6. I don't know of any on a four cylinder.
