New TTR Large bore manifold full race non FIA engines


We have developed this manifold especially for engines tuned above FIA Homologated Specification. It is for race engines of larger capacity than the 1600 FIA unit or engines with larger valves and ports than the FIA version.
It features revised lengths and diameters of the primary and secondary pipes to optimise both power and torque. Tested on the dynamometer to be the best available.
The material is correct for exhaust manifolds, mild steel, not brittle like stainless steel. Easy to repair if you have a problem unlike stainless steel which require specialist repair. Not possible at a race circuit.
