The Janspeed De-cat pipe replaces the high-flow catalyst on the Janspeed Manifold. The pipe is designed as a bolt on item and allows you to quickly change from running a cat to de-cat. Using a de-cat pipe further increases air flow and therefore improves bhp and torque across the whole range. The de-cat pipe is for off road or track use only. Image shows the de-cat pipe fitted to a Janspeed manifold (not included). 

Please note
The listing is for the de-cat pipe alone - you WILL need a manifold section to fit this to your car. This product will NOT fit with a standard manifold.

Also, replacement gaskets are not included. However, we can supply gaskets for a small additional cost - please contact us for details.
