Provided that I get my Stimulus check on time, I'm probably going to order a Cat-back exhaust for my '06 EX Coupe. I can't decide if I want the TiC or the Evo2 exhaust.

Does anybody have either of these? How is the tone of each? Notice any improvements on hp/gas mileage (I figure it'll be subtle if any). Bolt on fairly easily? Anything to look out for?

Thanks in advance...
