Thermal R&D has plans on releasing cat-back exhaust for P5
 

I recently wrote to Thermal R&D requesting info on whether they had plans on manufacturing an exhaust system for the P5. I have always liked their exhaust systems, especially how they sound. Very deep sounding systems and good quality as well.

We have done the pre-inspection on the vehicle and do plan for a system. I would expect something to be available in the fall or winter (we generally don't prototype in the summer as it is our busy season). Keep checking the websites for info.

If anyone is interested in getting an exhaust system from them, I suggest bombarding them with emails to show there is definitely a big market out here.
