Awesome! Glad to hear it. The website should answer a lot of questions for other prospective buyers.

Just an UPDATE: After having the Fast Intentions exhaust and HF cats installed for about 2 weeks, I have gained 1.5-2.0 MPG on my AVERAGE fuel economy! I am now at about 23.5 MPG average, whereas before I was at about 21.8.

My testing procedure was as follows: At the beginning of each work week I reset my average fuel economy and then drive to work/gym/supermarket/etc. as normal. At the end of the week (5 days), I simply record the average MPG. My commute to work and daily driving habits are very consistent during the work week.

During the first 2 weeks BEFORE the exhaust/HFC install I recorded just around 21.8 each week. For the 2 weeks AFTER the install, I recorded about 23.5 MPG average. Since the install was done on a Saturday, I was able to put a good 100 miles or so on my car so the ECU could "adapt" to the new modifications before I started the MPG test.

I got mine installed. Details over in my journal thread starting on pg 19 or so. The short version: I've got Stillen headers and Berk HFCs, which of course raises some fitment issues. Luckily everything worked out fine under the car with crossmember/swaybar clearance, etc. The tips came out slightly too high, so I spaced down the rear exhaust hanger mounts with some washers to correct it. Initial impressions are great, but I wanna let it burn in for a day or two and test it more, and then more details, information, videos, and pics will be coming on Saturday. This is about all you get for now - this is a pic when the car was still on jackstands in my garage, before I fixed the fitment of the tips:
