Kooks Headers Turbo Downpipes

Kooks Headers turbo downpipes are made from heavy-duty, crack-resistant, large diameter stainless steel. They feature smooth-flowing mandrel-bent tubing and are available in styles that connect to the original equipment exhaust system or to Kooks cat-back systems. Either way, they create power and improve performance. Kooks Headers turbo downpipes are offered in three versions: * Off-road (non-catted) for full track use with no horsepower loss and the loudest exhaust tone * With high-flow catalytic converters; recommended for street driving with little or no horsepower loss and a deeper exhaust tone * With Kooks ultra-high performance GREENCATS catalytic converters; designed for naturally aspirated and forced induction engines, they eliminate 90 percent of "Check Engine Light" warnings Note: Kooks Headers turbo downpipes may not be legal for sale, installation, or use in some areas. Check your state and local laws. Show Less
