CarBone active bypass muffler

It is an exhaust system component consisting of two separate silencers. It is also equipped with two electronically controlled valves, that open giving you the louder sound. The exhaust system is equipped with two beautiful central pipes.

The loud valves are controlled by a radio switch, which is easily mounted on the dashboard next to the fog lamps and the heated windshield controls. The connection is made by means of the ignition cable and the ground cable.

Our exhaust system is made to fit any SSI early style exhaust manifolds. We decided to do it that way because of the power increasing potential and meanwhile keeping heat exchangers (they are responsible for heating the interior).

Plug and play. The installation is very easy. Just the rear bumper needs to be reshaped for the installation. In the F model, 964 you can cut a piece of the central part of the bumper. In the G model just remove the bottom part of the bumper. 
We can modify and supply the central part of the bumper to make it fit perfectly.

To fit this exhaust in 964 models there will be needed a modification of the exhaust manifolds.
We offer dedicated exhaust manifolds matching each type of F/G-model, 964 engines.
