Title: xbr500 exhaust system
Post by: rocker on May 30, 2009, 09:12:15 PM: Hello all, hope someone can assist. I have an XBR500 1989 and the exhaust downpipes have rusted through. I have contacted David Silver spares to get replacements, but they only supply the left pipe (full exhaust unit) and state that Honda have discontinued the right unit. Any compatible downpipes out there? Best place for second hand spares?

Thanks to all considering response.

Best Wishes
Rocker

Not necessarily the cheapest - the guy quoted me near as dammit £500 for a full system and I'd have to let him have my existing set to check his jigs, but .....

You're welcome

Will wait patiently for a pair to appear - either separate from breaking bike, or from complete bike, £500 for exhausts, you can get a full XBR for that (almost). Have sourced the parts from a German company after entering part numbers onto internet, but again approx £500 for the set and a bit too rich for my blood.

Thanks to all for responses.

Only problem here is I have to remove the old pipes myself as OS wll not (although OS will fit pipes and silencers after removal) and have already managed to shear one bolt with very little effort!

What sort of money (if you don't mind me asking)?

Post by: guest564 on June 23, 2009, 05:19:26 PM: Pipes will be twin downpipes, same shape as the originals but 35mm bore. Cost is £180, he did say that if we'd got together it would have been £160 for two sets the same (bent at the same time). I reckon that they should work quite well, even the XLs used to run bigger downpipes back in the day. White Brothers used to sell them, I think they were made by Supertrap.

Post by: guest564 on June 24, 2009, 12:20:12 PM: I didn't ask, I would assume captive flanges because of the bigger bore. I've sent off a deposit and I'll talk to him again in a few days to finalise the details. Incidently I measured the HRC pipe, the downpipes on that are also 35mm.
