Unfortunately my left backbox has disintegrated - the pipe facing the front of the car has rusted through.

Not unexpected after 235'000 km and 18 years I suppose, but I badly need a replacement for both sides soon.

I replaced the broken one with one of the pristine X-power backboxes I have - lovely sound but too much resonance around 1'800 - 2'200 rpm for long-distance cruising, and I use my car for long drives a lot.

Does anyone have some standard ones in good condition?

I have a trip to Chichester (W Sussex) planned in mid-October so I could collect if you're not too far from that area. Otherwise I'd pay for courier and packing.
