I'm in need of a new muffler, but don't care to attract a lot of attention.....

Its not all too loud. Has a nice satisfying tone. Not loud like B&B or Eisenmann. Drones a little bit between 2600-2800. The tips are MASSIVE. You need to trim out nearly an inch around the existing exhaust cutout. But they look great. Note also that it takes a LONG time to break in. At least several thousand miles. I think mine only reached its full sound this summer after I actually drove the car enough to get it running hot for more than a few minutes.

Note that these are easily adapted to fit a 535i. Bruno has the writeup on his site.

Btw, the seller is likely making a significant profit on this. RD clearanced these out for $150 about two years ago. I don't think they are still available.
