I have the Miltek's on mine, and I truly enjoy them. Not loud and obnoxious (subjective) like the Kellners, but a nice tone. You will find out very quickly if you travel in the wrong gear though
The interior of the cabin has the tendancy to BOOOOOOM if you try to accelerate from too high of a gear. I think this is a symptom of all after market exhausts though.
Good Luck, you will enjoy it none the less.
