Can someone please PM me with details for an MOT garage in London that can test my scooby. It has a decat pipe fitted.

 

In other words, you want to know of a dodgy MOT station who will accidently stick the probe up someone elses exhaust pipe instead of yours!
There are places that will fit a cat section to the car, test then replace the de-cat section. It's getting harder to find a garage that will do it as per my first paragraph as VOSA inspectors can arrive unannounced.
I know someone who does the second method but he's out in Essex.

If he ain't too far out into Essex then I might have to pay him a visit. Can you PM his details please.
