It's my girl's bike and I'm not that eager to join a Yamaha forum since I've got my Honda CBR, BUT maybe someone will know here...

I need to fix a dent and small crack in the exhaust tip that's riveted on. I figured stainless but decided to do some searching and I'm not finding much good info since most people try to replace their exhaust, not continue using the stock for usually dumb reasons.... Alas of all the info I sifted through I'm seeing some say the factory tip is stainless and then I see some others saying it's titanium, and then I see some saying it's a mix of titanium/SS and using SS filler rod is ok.

I can do the spark test BUT if someone knows for sure it'd help Looks like white sparks and a fair amount of em it's Ti and if it's orange and somewhat sparse in sparks it's SS .

Well shit... in big bold fancy laser cut print it says exactly what it's made out of. TITANIUM.... This should be fun

Always a good learning experience. Anything thin is a good way to learn quick.

especially if it's cheaply replaceable and not integral

If I don't wanna drop the cash for Ti filler, I understand the Silicon Bronze might be a good alternative? I beat all the dents and the two small cracks back into place so it's like .5 mm crack width about 5mm long right at the very end of it. Worst case it fails but it won't be an issue just need to know if Silicon Bronze is a worthy metal to use.

I think it was the Yamaha R6 forum, but it was one post of someone saying it was a great alternative and something they did a few times. I know in general it's good for joining (brazing) dis-similar metals but this is why I'm asking not telling.

Can't say I've heard of that. I'll have to look through my Titanium information depository.

I feel like for an whist silicon bronze or any brazing may not be the best. Not an exhaust or Ti expert but I do know exhaust gets hot and if it gets too hot the silicone bronze or braze metal could get a little soft and cause you problems and it will also wear a little quicker. I'd personally recommend actually welding it with Ti filler or a replacement.

i have never brazed TI but have brazed (OA) tabs on two stroke
expansion chambers to attach spring to the cylinders more
times than i can count with out failures or melting.
take this info for what its worth.

I found someone on ebay that sold Ti rod by the stick. I'd imagine that an exhaust tip wouldn't take much. I just had to weld a broken tab on my Yoshi pipe, so I just bought two sticks from him & it worked great. I can't remember exactly how much it cost me, but I'm a cheap bastard, so it couldn't have been too far out of line...... Good luck

Thanks man! It's coming up soon, just fixing everything else along the way. I got time since we're waiting on customs for some China parts. Tis the season!
I ended up buying Grade 1 Titanium from TiCon. I also got a 10% discount code anyone could use for any first time direct purchase
I got 1/2 lbs of 1/16 rod so I got about 27 total rods. I'll probably be doing what that guy did and sell all but the one I need and maybe a couple just to say I have it laying around. You're more smart than I am
I really do not see Ti in my future besides this and if I do then obviously I have the need for it, and the cash for it so buying another box won't hurt. Besides the money, I did say that mostly about stainless and steel too but I've been welding both more than I thought
