Review on FIERCE CYCLE Universal Motorcycle Muffler by Richard Cartner

This finally solved my problem. I replaced the exhaust in my Porsche Boxster S with a 3.2 liter boxer engine. I removed all 4 cats and reinstalled the headers with a much lighter and freer exhaust. A new air intake and a massive cold air intake were also installed. After the mods the car got too noisy (in a bad way) and I lost torque at low revs. I tried several other screens and experimented for some time before I found this one. I have not yet tested the final results under pressure, have not tested them and will not verify them before driving some serious kilometers in the car, but eventually after a few hours of driving. Sounds perfect and has a good power curve (trousers spot test). My last combo ended up with 1 stainless steel washer put in the exhaust pipe and then with this baffle, I did this on each side of the dual exhaust. I used a drilled bolt to hold everything in place, but it could be welded on if desired.
