View Full Version : Stainless Exhaust Elbow Thickness?

05-29-2012, 02:55 PM
Need to fab some custom elbows for my aftermarket exhaust. Going to buy 316L Stainless tubing for the project, but have no idea what the wall thickness should be :bonk:. Would this (http://www.ebay.com/itm/Stainless-Steel-316L-Round-Tubing-3-OD-0-065-Wall-12-Length-/140654809642?pt=LH_DefaultDomain_0&hash=item20bfae122a) suffice?

Double wall to allow passage of cooling water?

Single wall- wet exhaust

Wet exhaust elbows are double walled, the water has to be injected at the end of the elbow so to prevent revision.

Is this only when using stainless elbows? I'm using Imco Thumper Power manifolds....water mixes with exhaust at the back of the riser as it exits. Do I still need double walled elbows in this case?

I'm holding a Stainless Marine Elbow in my hand and it's measureing 7/64" thick

Thanks guys, I think I found something thicker than that .065 which should work.
