Here are some pictures of my horizontal manifold pipe. I know many have had trouble with theirs splitting at the welds. Mine did to, but then later blew out in a new place. I have sent the pipe to the guy in Tennessee that repairs forged wheels. Frame Straight is the company. He is a miracle worker with metal. All of the pipes cost 870.00 we will see if I save any money. The sheet of metal is expensive, and I understand it will either be tented or gas filled. Has anyone else ever had one repaired? Do you have one lying around, I'll buy it.

Added metal and blew again in 1000 miles. Losing money fast on this one. Can this pipe be purchased even used?

Get a fabricator to make a piece to fit. IT IS OF THE UTMOST IMPORTANCE TO CLEAN ALL THE CARBON INSIDE the exhaust where the weld will be. The guy who is welding it should be a competent trained welder and not a hack at a muffler shop. Tent isn’t necessarily. Plug both ends with bungs (even tape will do in a pinch) and feed a tube in one end and purge with argon while welding.

This is the second patch. The new failure does follow a seam. But the crack out in the field is so irregular. I think the newer version of this pipe is round without seams.

This happens quite often after a repair and I have no idea why. I always tell customers this may happen and I can only guarantee what I’ve repaired and not the cracks or blowouts that happen around the repair. It’s infuriating. I can only guess that the damage has occurred over a wider area. The weakest part let’s go and after the repair, which is strong, the rest starts to go.

You have described it clearly. From what I can see online the new pipe has no welds, just bends. I tried a little experiment with titanium mesh and fiberglass wrap. Held for two hours and oddly did not burn through. I watched it running and the pipe swells and retracts. In the hole obviously movement was greatest. Then after 1 WFO run it opened a crack down the side. I think Termi failed to understand how much movement a flat spot gets at 700 degrees. I am forced to order the pipe kit. Ebay 870.00 +60 Shipping unless someone has a used set.

Sort of caught between a rock and a hard place. Somebody could fab the whole section but at what cost. Cheaper to fab using round pipe but then there’s the fairing fit issue. It’s close to a case of having to just bite the bullet and get a new one.
I would try to console you but damn-it. Your choice to buy a Ducati.

Just playing 96c. I don’t really mean that. 😃
Of course you do. You've been down the rabbit hole. At least we are not talking ignition or starter. You will not believe this. I contacted the Canadian importer EURO CORSA .COM. A very nice man Marco is contacting Italy. Yes in August the whole of Italy shuts down, but he thinks there may be a way to help me get the part I need.

Also learned about the welded header verses the newer hydroformed bent tube. Found a complete system in Charleston, Forwarded my phones and drove like hell. So this welding thing is resolved. If you have the welded version. Just buy a pipe kit from MOTOWHEELS and move on.
