Absolutely love the Kooks Headers + Y-Pipe w/ High Flow Cats setup. Evened out my exhaust sound and eliminated the drone from my Flowmaster cat-back system. Went naked; No Wrap and No Ceramic Coating per manufacturer's recommendation. They said unless they were going in a racecar, a show car, or something small and compact, that they don't recommend ceramic coating them. Note: the Kooks Headers and Y-Pipe ONLY work with one another.

Work awesome for my 07 300c paired them with slp loudmouth 2 and it sounds amazing. I had purchased the catless ones and i didn't like the smell og exhaust fumes and ut had ridiculous back pressure.
