I figured it would be something like that.
Since posting this thread, I received a quote from MSL of £500+VAT just to fit the rear box. The mid pipe included would be more........
The chap on the phone did the great sell that they have fitted hundreds of them etc and I fully expected something like £200-£300......but was taken aback with the quoted figure.
He couldn't explain why it was so expensive - it equates to 9.1 Hours to fit an exhaust....given the rear box is the easy bit, I have done several cars where the exhaust rear boxes haven't needed any cutting.
I cant deny that the wiring needs time and effort to get right but come on!
What am I missing?:fail
I do want a quality outfit to do the work but it seems very very high!
