Even though the Fitment Factory says they can make it fit, wouldn't the piping diameter be too big? I believe the pipes are 2.5" diameter and the exhaust is designed for a 5 liter V8 engine. IMHO, a V6 with half that displacement would not do well with such an exhaust. Making it fit, and making it work properly are two different things.

The PPE headers replace the stock exhaust manifolds and stock primary catalytic converters (which is the part that makes it illegal in all 50 US states)
