Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Custom Exhaust

I just had one of the rear mufflers on my Mondeo removed yesterday, and while I was there I made some enquiries into replacing the stock resonator. I was advised to get a resonator that has on open chamber in the middle of it. Apparently these work really well at stopping drone and the HP loss is very minimal compared to a normal res.

A place here in Australia custom makes them (Marathon Mufflers), but no doubt other companies make similar muffler.
