Yeah, I've got the MBRP street catback on order, hope to have it on in a couple of weeks.
Something I didn't realize about the Cobb tuner until after I bought it is that you can't tweak the tunes that come with it, until you take their online "Accesstuner" training course for $149. All I wanted to do was change the tire circumference for my new wheels, and gear ratio for the rear end, but I couldn't do that without the training course. This is the only tuner I've ever bought so I don't know it that's normal in this industry, but it took me by surprise.
