[M3 Montreal]

I personally love my catless x-pipe and exhaust AA.

If you want to hear some inside cabin and outside videos check my vidoes on Youtube.

Type in "montrealbmwm3" in the search field and you will find about 9 videos (track , roll ons, drifting) etc...

I can tell you with catless X-Pipe and exhaust it's quite LOUD in city driving and very nice on highway driving since you are never in drone range at highway speed.

Ive actually sat in a friends car and checked mine out from behind to see how the canisters look and I can say I actually LIKED the look of the silver canisters. It gives it a very different look that I like.
