What Straightflow states

Straightflow says the 420mm body gives improved sound reduction while keeping strong exhaust gas flow, and the straight-through perforated core keeps backpressure low with a deep, sporty exhaust tone.

It lists this muffler for 2 inch (50.8mm) exhaust systems, custom exhaust fabrication, naturally aspirated engines, small displacement performance builds, street vehicles needing better sound control and universal exhaust projects, and recommends professional installation.
