Universal competition exhaust parts

A complete program of universal parts for the self-construction of exhaust systems is offered by the company HJS. With this delivery program, each passionate motor sport fan has now the opportunity of designing his exhaust system individually. It is also extremely helpful for the reconstruction or replacement of original parts which are no longer available. All parts are manufactured in stainless steel.

The HJS competition boxes reduce the noise by absorption through centre perforated tube and high temperature proof fibreglass. Accordingly, there is less gas flow restriction and so back pressure is reduced and engine performance is enhanced.
