    Any intrest in custom downpipes? W-body

    I could make them in 2.5" or even 3" for around $100. I could also add flanges, flex couplers, and even long ones if you want the cat deleted. Let me know if your interested. If no one cares Ill just make one for myself lol.

    Coatings would also be an options at an extra cost ofcourse.

        so this would bolt on after the exhaust manifolds? It is a straight downpipe that would attach to the catalytic convertor? or there should be a flex pipe before the catalytic?

          This bolts to the exhaust manifold. It comes down then is attached to the cat. If you would like a flex coupler I can add one but its not there from the factory.

                so is this a direct bolt on with no modifications? Or I got to have the end that meets the catalytic convertor welded?
                Ever think about making a complete 2.5 catback or something?
                what type of ss are you using?

                  Theres no flange so its your choice, you can weld it or clamp it. It doesnt really matter.. It will be ready to put on out of the box..

                  I can you any material you'd like.

                      I could make a complete exhaust but it would be a little expensive.. dohc is selling complete exhausts (minus the downpipe) for $150ish.
