Review on TotalFlow 12103 Mini Race Exhaust Muffler: Premium 304 Stainless Steel, 2.25" Inlet & Outlet with Resonator by Steve Snyder

I have a 2006 Mini Cooper S with a full Milltek exhaust system. Problem: From WOT 4000 there were too many drones. When I was looking for an additional resonator, I had to choose the right one. This is a racing resonator and I expect a racer will need resonant noise reduction at 4K and higher resolution. This 10" Total Flow worked. Now 4k and up is tolerable. Mini Spec - Using a Milltek cat-back, this resonator replaces the link pipe with no mod. The reason I gave it 4 stars instead of 5 is because there is no RPM, tone, or frequency that the resonator is tuned or tuned to, I'm glad the educated guess worked.
