By-Pass sports catalyst - Porsche 964

This "bypass" version is a catalytic converter-free solution, consisting of a straight pipe and an integrated silencer. It is designed to replace the original catalytic converter, offering a freer exhaust gas flow, increased sound, and a significant performance gain.

Performance and features:

• Power gain: +12 hp on a stock Porsche 964.

• Performance note: The gain is 5 hp less than our 100cc sport catalytic converter version, because the back pressure is reduced by the highly freed flow.

• Improved sound: Provides a more present and sporty sound.

• Direct fit: Designed with the original interfaces, it fits without any modification in place of the catalytic converter, between the manifolds and the transverse silencer.
