Welding stainless steel tips to stock Ti exhaust?
 

Anyone know if this is possible? I know Rick@Moroso Performance said he "grafted" SS tips on, but he has not replied to my PM. I have heard that SS may be difficult/impossible to weld onto Ti...

Hi Troy,

I saw your pm today as well as this post.

I bought the tip only from SLP on ebay for $150.00. It was a blem. We fixed it up and had it chromed.

It was a small pain in the ass to adapt to the ti exhaust. Since the ti has two outlets on each side, and the tip only has one inlet on each side, we had to cut out the end of the muffler, make an internal adapter, and make a large one tube outlet to go to the SLP tip. We used stainless material and rod on the ti, and it seems to be holding up so far, but that is only about 1500 miles. It was not a fun job though, and there would be no way a normal muffler shop would or could do it for you.

Here are the pics I told you about in the pm I sent earlier.

Hope this helps!

Rick

Thanks for the reply Rick! Wow that sounds like quite alot more work than I expected.

I assume you went that route because either you didn't want the car louder or the stock Ti exhaust weighs less than the SLP stainless steel exhaust? If the latter, did you happen to find out the weight difference between the SLP Powerflo and the stock Ti?

Your best bet would be to cut the Ti tips off, and clamp different tips on.

I had an exhaust that was too loud so I bought a used ti set. I had to heat and bend the flange end because the rest of my exhaust is custom and the flanges did not line up. Because the exhaust had to be tweaked like that, the tips did not want to look right. I was going to make a big single tip for it, but then I saw the SLP tip on ebay. There is one on there now also. Search SLP.

This is what I was going to make.

This is the SLP tip.

Ahh. Thanks again Rick.

Generally speaking, in industry, we will never try to weld titanium to stainless steel. The two can be joined but the resulting joint will be brittle. We will weld titanium to something like zirconium. You can usually join any non-reactive metal to another non-reactive metal, and join any reactive metal to another reactive metal.

Having said all this, I would expect this dissimilar metal joint to fail at some point from cracking due to fatigue. Just the vibration from the running and heat cycles are sources of fatigue. Also, stress such as backing into something, will cause failure.

The interesting part is the difficulty in determining when it will fail. I ain't the one who can answer that. So if you have found someone skilled enough or can find someone skilled enough to get the two to hold, shine it up and enjoy it!
