Lightly used, but still great. Loud at WOT, most noticable at 3k-4k and just before redline. I'm sure it will scream in lift.
Fits GT and GTS, it's intended for the GTS, but it fit onto my GT problem free.
Comes with everything except one of the clamps, which is nearly identical to your stock clamps. It also comes with the box and bags and whatnot, there are NO INSTRUCTIONS, but it's easy to install without them and if you get stuck, the install is the same as the other Intakes
(which all have install guides on here and on that other site).
Oh, it's been bog free for me, and it will only CEL if you install it incorrectly.
