Since we do not settle on making a better sounding-only exhaust, but rather insist on getting the most performance increase, the systems we have developed include a straight-through, smooth-bend oversized Turbo Downpipe, which eliminates the restriction of the stock catalytic.
We then designed a twin pipe exhaust, equipped with a set of HJS Motorsport, high flowing twin, parallel metallic cats (Y-pipe also available in a cat-deleting version).
As the final result, we guarantee a massive drop in exhaust gas back pressure, and a substantial gain in torque and max Hp.
