Manufactured Like No Other.

Each of the Fuji Racing Exhaust Manufactured to perfection. Each exhaust manifold is welded by a computer assisted machine to give 100% weld accuracy.

Manufactured from SUS304 stainless steel. Tubing is 1.5 to 2mm thick and 10-12mm thick exhaust flanges depending on the application.

Due to the SUS304 construction, the exhaust manifolds are also significantly lighter than the OEM counterpart.

Exhaust collectors are manufactured using the ‘lost wax’ casting process this means each collector is as smooth as possible to increase exhaust gas flow.

Slip jointed to allow for expansion when hot to reduce the risk of stress cracking.
