Repairing damaged exhaust... parts source? - Ducati.ms

So I have a set of used carbon arrow high-mounts for my bike. The seller said it had light rash on it, but it turns out one of the mid pipes is trashed, and there is slight damage to the carbon. So in the end i got screwed.

My question is, can drill out the rivets and replace one or both midpipes? do you think i could have some pipes made locally? this is the piece i am talking about, not my bike but its the same system.

I think the cheapest fix would be to wrap the pipes, drill out the rivets and swap the cans from left to right.

I am not sure I follow. Why would I need to switch the cans? The cans are fine, I just need the mid pipe on one side. Or I would remove both mid pipes and have them replaced.

You mentioned "there is slight damage to the carbon", and he suggested swapping the cans to basically hide the damage to the carbon, unless there's carbon on the mid pipes?!?!

Yes VERY slight damage to the carbon, but it is fine. Also I can just switch sides because of the mounting points on the cans (or i would have to switch the tips as well).

The damage on the carbon is livable and almost invisible. My real concern is getting new mid pipes. Sorry for the confusion.

I think finding someone to remake the mid pipes would be cost prohibitive. Your cheapest option would be, as said before, to wrap or if the damage isn't too bad, sand and repolish, or paint it with some heat temp paint. For a little more money, you could have them ceramic coated. I have never had it done but hear it's very reasonable in cost and many different color options:

Zircotec high temperature coatings, ceramic coatings, engine, automotive and motorsport, exhaust manifold and header coatings.

Or, sell them on ebay and buy what you want.

Actually just take the bike to your newest muffler shop and they should be able to make you a new midpipe. Its the headers that would cost you but a midpipe any muffler shop should be able to replicate the bends.

ok gyus.. i snapped some pics.

the "damage" to the carbon

Here is the damage to the mid-pipe... it doesn't look bad, but it is bent

personally that little amount of damage I wouldn't worry about, unless you want show quality. If you're really worry about the mid pipes, it looks like you could polish the scratches out, the dent is hard to see (at least in pictures), if it worries you wrap it in a nice exhaust wrap and no one would be the wiser.

I had a dented staintune ss header and it was really caved in. Put some water in the pipe and put it the freezer oriented so the dent is below the water line. Wrap the dented area so it freezes last. Check it periodically so it doesn't over expand and crack. Repeat if it hasn't pushed it out over night. Mine took a couple of cycles in the freezer but the result was good. I mean the pipe was seriously dented and I couldn't believe how well it worked. Went from a crescent cross section, fairly creased at the edges,to round with just a slight indication of where the edge of the dent had been.
Alternatively, if you have a straight shot down the pipe to the dent you may be able to get some sort of drift in there and tap it out. Then just sand and buff a little and voila.
