I'm in the process of slowly taking my car back to stock. I just had my Gintani rear section uninstalled and it's ready to go. I only had a chance to put about 800 miles on this exhaust, but it sounded wonderful. The larger tips also fill up the rear bumper section very nicely. Weight savings is great on the track, and I am happy to report that this system is MUCH light than stock. I'm asking $1550 shipped.
