They are used in some of the highest hp M3 dyno charts available (including my car). I don't see the downside to them over catless at the moment. I was happy enough with their performance that I now use them in our STi/EVO builds.
Fast Intentions also builds Gintani Xpipes for them as well as their catbacks, which basically consists of Sebring mufflers.
