EXPORT PRICE - No Vat charge: 1863 .80 GBP

A bigger bore version of our successful 48mm design! The 4-1 collector steps up from 48mm to 51mm and it's exit is now a 70mm bore! This fits to our 70mm bore TVS 1320 exhaust system. This design can handle power outputs up to 400bhp, although that figure required a lot of engine mods! Typical outputs of 350bhp have been achieved though. (NOTE - not a 76mm bore - lose boost/lose power!) The install shown was built with a V-band connector between catalyser and silencer - ask if you would like that layout.

The HJS HD catalyser is the 130mm dia design used on our V6 installs.

Lead time - special order but I will be building five of the 70mm manifolds next week.
