Starting with a 3/8-inch thick stainless steel construction, this header flange from Kooks is built to handle the demands of your 2014-2016 Chevrolet Corvette. It's designed with oval ports specifically shaped to match 1-3/4 inch primary tubes, which helps ensure a good seal when you're installing your headers.

Kooks has been in the performance exhaust business for a long time, and they build these flanges in the USA from T304 stainless steel. This material is chosen for its strength and resistance to corrosion, which is important for a part that's part of your exhaust system. Each flange is tested on dynos and in racing conditions, so you know it's made to perform. This particular flange is sold individually, so you'll need to order the correct number for your specific header setup.
