I'll most likely have a m5 rear in a couple months, but I'm not sure which exhaust to get. I'm looking for something that doesn't sound high pitch like ricers. Any help? I want RD Sport but it was kind of too much for my budget.

Is the RD Sport Quads with chambered mufflers, or straight through resonator type?

RD Sport does not disclose their muffler design type (suppose to be a secret), but they say there's no drone issue. Vegastrashed had it on his former 5er. Personally, I think they are straight through design.

It seems rather impressive if they have straight through mufflers, without any resonators, and no droning.
And also keep the sound at acceptable level.

Could someone with RD Sport system take a flashlight and look into the pipe?

I have yet to listen to an RD sport setup both inside and outside the car. Can anyone post a video clip especially from inside the car on acceleration?
