As I mentioned to the guys.. I’ve now purchased two Gravity Performance header pipes for two entirely different engines and BOTH have been truly revelatory in terms of performance boost. First is their 4-2-1 headers for the Mini R53. It’s advertised as being for cat delete but I fitted a 200cel cat and then had a custom GrpN single silencer system made. 251whp from a supercharged TomCat BVH JCW on 440cc injectors, -23% pulley , ProRacing.pl piggyback OBD3 😎👌🐎 and a 175mm velocity stack w/o any filter whatsoever inside the JCW airbox fed from the windscreen scuttle only ( thus totally sealed cool damp inlet charge). Run on Shell VPower.

The second engine is a n/a Subaru EJ25 installed in my VW T3 van with yet again a punchy as hell equal length header pipe from Gravity Performance into a short straight thru silencer and 175mm velocity stack sealed cold air intake . Standard engine apart from 4kg alloy Mishimoto flywheel to add zipp on n comparison to the cast iron original at 11kg!!!!. Pushing out circa 160whp… as yet untested 🤪
