Made of 100% Brushed stainless steel it bolts right up to the factory exhaust headers and provides a tight seal with the new set of TORCA clamps that are also included with the Test Pipe kit.

The Test Pipes features a ** Z STYLE ** expansion slot at the rear of the Test Pipe to provide that tight exhaust gas seal with the help of the European designed TORCA style clamps. These clamps are strong and robust with the beefiest in band width, a 14 mm shank bolt to provide the highest degree of load when tightened.


An additional support brace is also provided (just like the factory) to relieve the load and stress if installed.


The gains in horsepower is achieved through the free flowing design of the Test Pipes and the replacing of the factory primary catalytic converters by removing the restrictions of the OEM cats. They will turn on the check engine light. With guaranteed HP gains this application is a must for the track user .
