It's a universal muffler that you will have to fab up parts to get it to work on your car. The muffler can be bought directly from SpinTech, they are in SoCal so if you live down there look them up and you can probably just go pick one up from the factory instead of paying for shipping. The 2 1/4" dual inlet 3" single outlet I have cost about $130 for the just the muffler, plus another $30-$40 in bracket pieces and exhaust pipe pieces and tube bending.

Nope all stock M20b25 with 192K miles. But I do work at a BMW shop so the engine is well maintained and anytime a part starts to go bad it gets replaced. I can hang with newer stock mustang GT's with 5speeds or slightly modded ones with auto trans. The look on their face is priceless when I stay next to them with my old 3 series is priceless. My E30 went mid/low 15's before the muffler and K&N with a bad O2 sensor. The dyno #'s in my sig are with the K&N only and the same bad O2 sensor. I want to redyno since I just did a valve adjustment, new spark plugs, muffler, and new O2 sensor.
