Welder friend blew a hole through it when attempting fix. Does anyone here have one to sell?

The Agostini Y-Pipe is a last resort as I really, really like the stock power profile.


Thanks!

Good luck. The pretzel is now made from unobtainium.


Don't even consider the Agostini. The Arrow Ti midpipe works. I run one on my GRiSO. I can tweak the map to compensate for the one less 90 bend.

Thanks, Beetle.

Hunt now on for the Arrow Ti midpipe.

Jeezus Jin. You already know the best welder in Seattle. Before tossing it in the bin, give a real artist a try.

My experience with exhaust pipe repairs reminds me to braze them rather than weld them.  A weld is too brittle, and will probably crack again under duress, whereas  brazing seems to hold together.

Certainly won't do any harm to try.  Smile

Edit:  Just remembered that the stock 'double-silencer" was swapped out early in the peace for a single Mistral that I had lying around.  A lot less weight for the crossover to deal with.

LoL. But, but, but... it's pedestrian stuff. Not Art. (Joking. Love ya, Pete!)

Actually, I'm kinda shy about that kinda stuff: favors and obligations. Maybe it's an Asian thing. Very Happy

Agreed on brazing. Bad judgment on my part. Original plan was to beg at the back door of a local custom bicycle frame shop. The crew there braze and TIG weld thin wall Cro-Moly all day long.

In any case, ordered two Arrow Ti midpipes from Italy last night. Fingers crossed they arrive. In hindsight, that's kinda paranoid, eh? Source is: [You must be registered and logged in to see this link.]

I have a stock Y-pipe but I'm pretty sure it's cracked somewhere even though I don't see anything obvious. It had a bad exhaust leak until I replaced it with an Arrow Ti pipe and it runs so much better now, even with a mild torque loss (it's not super noticeable after a few days of riding it).

I got the 2-1 arrow mid from these guys, shipping took 1.5 weeks. It was way cheaper then any other option I found.
