We loved this very clean 2015 Chevy SS. This customer reached out for the install of a full Kooks exhaust (1 7/8″ Long Tube Headers and Kooks catback). Not only did it look great, but it also greatly improved the exhaust tone as well. With a free flowing exhaust it’s now ready for a cam swap or supercharger install! After dyno tuning, the build yielded a 55 rwhp & 45 ft/lbs tq gain, ending up at 403 rwhp & 404 ft/lbs tq!
