Sounds almost like stock from inside the vehicle. Just some added turbo whistle. But outside, under a heavy load, sounds throaty and definite turbo noise

Great craftsmanship at Kooks. My car had a stock exhaust minus mufflers. It was loud and deep. The Kooks exhaust has a deep growl. It is not loud relative to what I was used to with no muffler. No drone at 2k rpm anymore. Fitment for the stock 14 GT is not exact. This system has 3" tubing. Even though it is described as Catback it is really a resonator back. The stock H-pipe will not connect directly. You will need to mod H-pipe or buy new H/X pipe.
