I have FatMat sound damping in both front doors, sliding door and rear hatch. This makes a big difference in the interior noise level. My biggest noise problem now is the GW stainless steel muffler. It's a straight through design and really resonates at certain rpms. I have an OEM replacement (Bosal) that I'm going to try out. -Mark On Sat, Nov 3, 2018 at 9:32 AM Dan N <dn92610@gmail.com> wrote: > I am not an acoustic expert but I do believe in resonance as in musical > instruments and drums.
