View Full Version : Exhaust Conversion Dual > Single ?

Has anyone ever converted a dual exhaust P38 to a single exhaust system?

Comparing a 4.0 single exhaust system with 4.0 dual exhaust truck, it did not strike me what the differences were.

I am not changing the cats, so just the center muffler and tail end resonators.

Anyone know any reason why this may not work?
