Kooks Headers Y-Pipes
Y-pipes are usually used to connect to original equipment exhaust system connection points. Kooks Headers Y-pipes are heavy-duty and crack-resistant, featuring large diameter stainless steel construction with smooth-flowing mandrel-bent tubing. Most are designed to be used with Kooks long tube headers.
Kooks Headers Y-pipes 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 up to 900 hp, eliminates most "Check Engine Light" warnings
Note: Kooks Headers Y-pipes may not be legal for sale, installation, or use in some areas. Check your state and local laws.
