Overview
Kooks Headers H-Pipes
H-pipes create lower end power and are typically used for street cars that need performance with a comfortable sound level. Kooks Headers H-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. Some applications require cutting the factory exhaust system. Select models connect to OEM connection points.
Kooks Headers H-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 H-pipes may not be legal for sale, installation, or use in some areas. Check your state and local laws.
