Topic: Copper Exhaust..

[garrywarber]

Well its copper pipe 1 me 0.   I'm not discouraged yet. Coming up with a new plan on bending it,  stay tuned!  

Well, I doubt it would be easy to find long-turn 90's, so I'd use two 45's and straight pipe pieces.  Or go have a muffler shop bend them with their fancy insertion bending tools?  Fittings may not look as graceful, but it'd work.

Lookin' forward to the pics!  Could you tell me the proper flux to silver solder copper pipes?  I have an oxy/act torch and some flat sticks (don't remember the silver %) of silver solder already.

 you should not need flux with silver solder just make sure your copper is clean i would braze the joints if there not socket welds if you use copper wire for rod you could polish the joints they would appear seamless i think its very hard to weld copper with copper though, seen it done on tv one time

Yeah, braze sounds good to me too, at least pipe to mounting flange.  I may do a plumber's job and use fittings for turns...

Yep going to go pick up some 45* elbows after work. I think the key thing is to keep the fittings far from the head as possible as to keep the braze from melting out. I wish I didn't accidentally run over my temp gun last week or I would see how far to put it. I think braze can hold up to 900* before melting, I'm not positive on that though.

Exhaust temp could be at 1100 F

Yeah I know, that's why I wanted to make it one piece. A guy at work told me to put a stiff spring on the inside and one on the outside to see if that stops it from kinking. I was thinking just making them straight pipes coming off the engine. No bends but I may loose some performance on the bottom end and it will be much louder

lol I bought a stiff spring so we'll see what that does with some heat

JUst a thought, would a conduit bender work for you?

Are you trying to bend hard-drawn?  If you got it at Lowes you must be...  Annealing while heating will help, but the muffler shop would do better if they will bend your pipe...  You can get soft in L-weight, but in a small ammount it will be hard to find.  Maybe we will both end up at http://www.robertsonstorquetubes.com/index.htm ?

I've gotten really busy here lately and haven't had a chance to getting to the copper exhaust. My girlfriend wants to run super stock next year and she has a 12.5 Briggs I may test it on her first.I will post what I come up with soon
