Guest Posted January 30, 2007 Report Share Posted January 30, 2007 Thanks. I need a little practice with stick welding, as you can see from the most left weld of the downpipe. I guess I take those to school and weld 'em with TIG. Quote Link to comment Share on other sites More sharing options...
Guest adegnes Posted January 31, 2007 Report Share Posted January 31, 2007 would be great if you could post some info on how you manufactured the exhaust manifold... Parts needed and stuff... Quote Link to comment Share on other sites More sharing options...
Guest Posted January 31, 2007 Report Share Posted January 31, 2007 There was really nothing special in the making of the exhaust manifold. The materials I found from junk pile next to a food factory. I used the gasket to measure the flanges, and drilled & milled them out of 120 x 10 mm AISI 304 stainless steel bar. The pipes are 316 or 304 stainless, the 316 should be used, or if you can get your hands on 321, use that. www.burnsstainless.com has much great info about materials. The collector is made with angle grinder. With a milling machine it could have been made better and more easily. The rest is grinding and TIG-welding. You should feed the welding gas (argon) inside the pipes when you are welding. That way the welds don't need any grinding after welding and it makes them stronger too. If you want to make the manifold really good, make a slip joint or other flexible joint on every primary pipe. That way the manifold won't crack. It's preferrable also to make seperate flanges for each primary. That's because the high thermal expansion charasteristic of stainless. If the flange is one piece, it could rip the studs from cylinder head when it's expanding. Quote Link to comment Share on other sites More sharing options...
Guest Posted April 22, 2007 Report Share Posted April 22, 2007 Downpipe welded. The two sections will attach via V-band clamp. Quote Link to comment Share on other sites More sharing options...
