I need a cat though, those are catless. Reason is because Colorado is too strict it seems. I know just keep my stock and replace every two years for the test, but that's annoying and I'd have to harass my friend every other year and if he can't well I have to either buy tools to do it myself or pay someone.

I have not gone for the dp pipe yet... I have upper&lower hahn cp and, hahn cai was a xmas gift and I have not seen much diff in power just better throtlle response. so I vote dp although the blow off is soooo sweet. and I am not sure but if you pass the emission trucks that they have on the onramps to all the highways in denver area just twice a year you dont have to go in to get your ride emissioned just have to pay the fees when you get your tags. so I think that if you do get the non catted then just dont boost when you pass them as to not puff andy smoke out the back like a non catted dp will do and you should be good but again it is a risk though.
