Brullen makes an very high quality cat-back exhaust, and I've yet to see a better system for the MX-3. I've had mine for about 4 years, and I'll never want to, nor have the need to ever replace it. I currently have a 2 1/4" setup, with the "quiet" polished muffler with dual 3" tips. You can also opt for the standard (louder) muffler, a black finish (instead of polished) and can choose single or dual tips (3"-5"). You also have the option of hollow, resonated or angle tip. The kit is custom-fitted for the MX-3, so no modification is needed to install. The hangers are in the factory positions which made it so easy to put on. The sound is deep and smooth, but not too loud - anyone who has heard it agrees that it sounds really, really good. Also, it's all 304 stainless steel, unlike the Pacesetter and other systems, and has a lifetime warranty. The price is around $500USD and I think Corkport still sells it. I got mine a little cheaper from a Canandian online store, but the name escapes me right now.
Hope that helps a little.
