This muffler was specifically designed for a backdate to the st look. It is manufactured for mid-range and top end performance, all without drone inside the cabin. It seamlessly mates to ssi heat exchangers for added performance while keeping the cabin warm in the winter.

Ours are uniquely made with double perforated sound absorption tubes based on the halbgegenstromprinzip (half counter current principle). The acoustic silencer absorption tubes are made in a trapezoidal pattern and are perforated with varying diameters, which isolate and dampen the unwanted frequencies that c...(choose a part on the right to read more)
