The exhaust on the 540i is finally starting to collapse properly, so it's time to replace...

...the only snag being EVERY manufacturer in common use in the UK has the 540i exhaust classed as obsolete.

The only place left to turn at the moment is the bmw dealer, who want £713 ($1400) for a new centre/rear section. This isnt an issue of not being able to afford the cost - rather an issue of principle, not wanting to have to bend over and get shafted by dealer prices.

I CANNOT have a custom build exhaust on the car, it must be OEM spec or equivalent. As I'm 24 I cannot get insurance on the vehicle with a custom exhaust - half the insurance companies wont touch me with it with 'non-standard' wheels and seats in it.

Kinda stuck here - anyone got any ideas?
