Exhaust manifold downpipe source? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm running manifolds, rather than headers, on my '71 Blazer, and am having trouble sourcing the downpipes only (don't need the whole kit, just the downpipes). Anyone know someone who sells them?

Dusty, i just went to meinke and had them bend up a set. Not mandrel bent, not pretty, but they work. They even flared them for me. I used my old 2" pipes as a pattern, since have thown them out....

I'm scraping my whole exhaust in November. I'm gonna be using manifolds too. This place keeps popping up in the research I've been doing the last of months.

Might be able to use Summit parts to get what you need. Ive heard a couple of guys doing that before.
