Eurocode, can you make a TP and HFC with the 4" flange and I'm a buyer please!!!

cheers! mike
Mike, I think you may be mistaken regarding our test pipe and high flow cat for the B8 Chassis.

Both products feature a flange that is identical in inner diameter to the factory gaskets on the outlet of the turbo (approximately 3.5”) and the inlet of the exhaust (3.0”). Our test pipe features a smooth transition from the outlet of the turbo to the mandrel bent mirror polished stainless steel, all of the raw materials as well as the manufacturing is 100% U.S.A.

Our High Flow Cat features the same flanges as the test pipe, however we use a 200 cell spun metallic core catalyst that has a 3.5” inlet (to match the factory turbo) and we neck down the exhaust side to 3” to match the factory exhaust.

Both products feature retaining tabs that match up with the factory spring bracket to ensure OEM fitment.
