These downpipes are made to work with our z31 turbo relocation manifolds and relocation pipes. They are constructed of 3" 304ss, come with 2 o2 bungs, flex bellow.
Effective immediately, all downpipes will only come with vband flanges on the exhaust side. We will no longer be doing downpipes to the factory 3 bolt downpipe flange as they are the worst setup in existence. Also if you are ordering downpipe and relocation pipe/relocation manifold at the same time you will have to ship me your turbo exhaust side for exact fitup do to the abundance of turbos on the market. Also if you decide to order separately, you will have to ship me back your relocation pipe/manifold and exhaust side for exact fit. Unless I happen to have your turbo in stock Contact us if you have anymore questions.
