I recently got a good deal on an MXP catback from a buddy, only catch was that the resonator was a little scratched due to his car being too low. only the finish though and there was nothing wrong. I wasn't going to get an exhaust until later, but I couldn't pass this up.
I love the sound of the exhaust. it's very deep from 1k-4k then it starts getting louder from there on up. at idle, you can barely hear it with the windows down. with the windows up, I can't hear the exhaust at all at idle. this is a very nice sounding exhaust. I didn't want anything too loud but still wanted a deep sounding tone, and this met my requirements. I like it.
I do have to say though, installing the catback solo was a pain. I was like holding the mufflers up with my knee while trying to get the hangers on lol. took me about 2 hours. here's some pictures of the exhaust:
