(And before anyone asks, NO, I don't work for STEBRO. I live in SoCal and bought a Racing Muffler from them a couple of months ago and I LOVE it. Big sound, meaty and aggressive.)

So here's the deal: STEBRO sells 4 "systems" for the 986 and they fit both 2.7 and 3.2:

* System 1: Sport Muffler - This one just replaces the stock muffler. And it is about 1/3 the weight of the stock. This is the bigger (thicker) of the two STEBRO mufflers, the one that looks more oval. It has double chambers, makes less noise and less resonance.

* System 2: Racing Muffler - Again, this one just replaces the stocker and its even lighter than the Sport muffler. This is the one that looks rounder, like two long cans. Its basically a straight-pipe with some baffling. Pretty darn loud

* System 3: Sport Muffler (same one as System 1 above) WITH Secondary Cat-delete pipe - this is the System 1 muffler with a straight pipe that replaces the pipe-and-secondary muffler. Connects to the pipe that leads to the Primary Cat and the Header.

* System 4: Racing Muffler (same one as System 2 above) WITH Secondary Cat-delete pipe - this is the System 2 muffler with a straight pipe that replaces the pipe-and-secondary muffler. Connects to the pipe that leads to the Primary Cat and the Header.

Now go re-read the STEBRO weight descriptions of the EXHAUSTS (not just the mufflers) and the weights start to make more sense. The stock muffler and both secondary Cats do weigh about 75 lbs.

Like I said, I don't work for Stebro, but I think they are a class-act. Dan Petschenig, who is the head of the company answered all my e-mails and annoying questions and could not have been cooler.
