Our Corsa C de-cat manifolds are a good quality, UK made, durable product, which have been tried and tested for many years. Designed for easy fitment, the 4-1 is an easy bolt on performance product that instantly gives a louder sound and more power.

Replaces the catalytic convertor, which is required for road use, so track use only.

Bolts onto the original system for easy DIY fitment 

Approx 15mins to fit, after the standard manifold has been removed

 

Technical specification;

4 into 1 de-cat manifold 

Mandrel bent 1 1/2" primaries

We produce three primariy sizes for the Z12XE & Z14XEP, 1 1/2", 1 5/8" and 1 3/4" as the same manifold fits the Z14XEP. We tailor make the exit diameter to suit the system you have, either 1 3/4", 2", 2 1/4" or 2 1/2".  

For the more serious enthusiast, we can build one off 4-2-1 or 4-1 manifolds to engine builders specifications from £350.
