I thought it was a straightforward mod to install M6 mufflers on my 550i xdrive, but my (trusted) indy mechanic says the geometry/layout is all off and is a "waste of time." Can those of you who have done this give me some advice?

I thought that, if the 550 exhaust is cut off close to the mufflers, the M6 mufflers can drop right in (or close). Any advice is appreciated!

Looking to get this done in NJ/NYC area (too, if any recommendations).

Thanks in advance!!
