exhaust and supercharger for M6

[isee]

Not doing it just yet, but wanted to have an idea if there is a place (preferably in London) that does custom exhausts adn a place that can supercharge the M6 (doesn't need to be the same place)
Idea of prices would be good and how such things impact BMW's used car warranty?

thanks!

CA Automotive but for a supercharger you are looking at serious, serious money

If you want more performance I would do this: exhaust, tune, RPI scoops + block off plates, BMC Filter, power pulley.

Is it covered under BMW Insured Warranty?

Because that has a very clear term, something like "any modifications mean the car is not covered"

As it is an insurance policy rather than a warranty in the traditional sense, I guess this gives you NO wiggle room whatsoever if you put an exhaust on and, say, a wheel falls off.

If your air con packs up I'm sure they'll still cover it under warranty, if you stick on a supercharger and the engine blows up I would think not
