Installed today with one of my Subie buddies. Install took about 5 hours and made a call to corksport during install and they were very helpful. Make sure you have an O2 sensor socket and lots of WD-40. The directions were very good... Just remember where the lower heat shield goes after you take it off. It had me stumped for like 45 min. The only bad that happened was when I was removing the stock downpipe bolts it was so hard that when I got one to loosen my hand smacked something hard and I broke my middle finger.(notcool)
