I'd go spend the money on a tungsten bit and try to drill it out. Worst case scenerio I'd cut the flange off as close as possible and make it a slip fitting and just put a collar around it. You may also want to look at the welding/fabrication section on Honda-Tech.com They have some really skilled guys over there and I'm pretty sure a couple of reps for Miller frequent the forums as well.

 

Im going to the exhaust shop now, i will bring all your guys' ideas with me. THanks you much.

 

It sounds like he wasn't qualified to mess with it from the go, lost the gaskets removing the cat? how the f*ck do you just lose a gasket? It doesn't blend into the ground very well last time i checked Good luck with things.

 

Hey ok all is well. He was able to get the bolts off. 1 thing tho, he used some black gasket sealer instead of normal gaskets. Is this ok?

 

Like some sort of silicone sealant? I suppose it would do the trick, as long as it doesn't burn away. Might want to replace it with actual gaskets at some point down the road.

 

Silicone sealant? Did Mickey and Minnie say hi to the kids when you were there???

What kind of exhaust shop DOESN'T have gaskets??? You need to shop around better....

Rick

 

They had gaskets, just none that would fit. They used some black stuff that looked like tar lol. They said as it heated up it would seal and be good as a gasket.

 

Rule 1 - the only glue you use for exhausts - is WELD...

 

If it was like RTV sealant I would think this would burn off. You should get a real gasket on there.

 

RTV (silicone) should work but it is messy and might look pretty crappy. a half way decent exhaust shop should have had some gasket paper and MADE the gasket. 1 question though, after the guy at the shop said he could do it, and you were advised not to weld the ti, why did you take your car to a shop that obviously did not know what they were talking about??????

 

he never said he could weld it. he wasnt sure if he could. and i took it there because its the only one i know of. They other car speed shop around here wouldnt have been able to see my car when i needed them to, and they would charge and arm and a leg for the same thing

 

If you have a Ti y pipe, I would just take the time needed to drill and ream out the threads with a air die grinder and tungsten carbide cutting tip.
It won't take too long to do but take your time.

And skip anything that has to do with welding Ti unless your guys know how to work with Ti. Its very hard to weld. Its not like steel at all.

 

Here's a little info all...the simple realization is this - you buy a Ti exhaust, you better hope it never needs repair. The only really way to do anything with it, conventionally, is to cut and clamp it.

So how much would it cost to GTA weld a crack in a titanium exhaust? Also, where would I find such a person/shop?

 

Contact someone in the rocket propulsion or aerospace industry.

 

+100000000

and good luck!!!

Repairs here involve cutting the bad piece out and them clamping it to replacmeent pipe.

 

I thought titanium could be field welded? I know that there are certified welders capable of welding titanium, stainless, etc. outside of such industries. They might not be right for such an application, but they do exist.

 

When I researched this before...I remember there only being about 3 locations int eh US that can do this commercially...I don't remember anymore where and who though...none were SoCal Local..I know that.

Rick

 

Yeah commercially you are right. Industrial/Construction wise there are quite a few.

 

Yep - 11 - I'll see if I can find the info again.
