Well, I got the new exhaust on the car today and I am very pleased with it. After reading some posts I was concerned that it would be too loud, but I don't feel it is overwhelming at all. The exhaust note is natural and does not sound artificial like the 4" coffee can exhausts we have all heard. I was thinking about putting the old tips back on, but I have to say the round ones have really grown on me. Installaton was pretty easy. Boy I didn't realize how tight 65 lb/ft really was. I was worried I was going to sheer the bolt for that clamp, but I didn't.
As for performance, it seems to rev a little freer on the expressway, but around town I couldn't notice any difference.
It's worth mentioning that wUndercarparts was very good with the whole transaction and I would buy from them again. It was a good deal and I received a good product; I'm very happy with how everything went.
Here is a clip of me making a short 30-60 mph run. Note the widows are up.
