3 and a half years later.
I have found the gasket between the Y link pipe and the can has developed a small leak. It's a simple ring, 60mm ID.
Can I easily find a replacement? Can I hell! I've tried the UK distributor, aftermarket etc. Zilch. Even the factory in Spain referred me back to the distributor.
So, I went round to my local exhaust fitter, an independent, and after a rummage he came up with one.
Dunno the supplier but the item code is HAG10X. See the pic. There's also a code CEG49.
I had considered a three hole gasket between the faces, and that would have been the backup solution.
The new item is a ba' hair too big in OD to fit in the recess in the can end, but a wee bit of careful persuasion will see it in.
