This high performance exhaust system for the Porsche 911 | 964 has True Equal Length primaries. All primaries have a length of 870mm exactly. By using an equal length manifold, all individual cylinders work completely equally and you have the possibility to adjust each cylinder perfectly for optimal performance. Adding to that we have build a high flowing x-pipe design and there is room for the optional catalytic converters, heat-exchangers and heat protection. This exhaust system will be an improvement in all possible ways over the original exhaust. This will result in more horsepower and a much smoother running engine.

This exhaust system will fit Porsche 964 models with original and back-date bumpers with dual outlet. A single outlet is optional, please contact us for more details.

The wall thickness we use for the tubing is 1.2mm as standard (possible up to 0.7mm for the inconel version). The primaries diameter is 41.3mm. In all our merge collectors you will find a nicely finished cone, to improve scavenging and therefore a better functioning of the engine.

This exhaust system is available in stainless 304 (Celeritech's choice). For optional mild steel or Inconel in 0.7mm wall thickness please contact us.
