So i got around to installing my turbo back exhaust today, all i can say is WOW. I bought a downpipe from ebay for $85 shipped just to try it out since it was so cheap...to my surprise it fit up perfect to my UR test pipe. I also installed my HKS Hi-power catback to complete the system. I dont know for sure how much power it added but my butt dyno says . Quality and fitment of all the parts is amazing, very good craftsmanship on all components, i recomend this to anyone.
