I do have them. I love them more than anything else I've done to me car. I use to be bummed out about my car now I love it. I pared it with a magnaflow CBE and now I put my wrx buddy to shame, he agrees haha.
I also installed it myself, I was never that into cars before but now I do everything. It really all thanks to nasioc and doing my HW. It was an easy install. Basic hand tools set of ramps and a few beer. I had a friend help with the exhaust because we didn't use dw40 on the hangers.
The best part about doing the homework and installing it myself, a new found sense of how things work with my car.
