Get the Best Priced Infiniti QX4 Header Pipe

In the Infiniti QX4, maximum power and efficiency is attained by affording each of the exhaust valves a path for the exhaust gasses from the engine.

This collection of exhaust paths is called the exhaust manifold and it is comprised of header pipes.

Header pipes provide a path that allows for the efficient exhaust of gasses without the creation of back pressure that could feed back into the engine and reduce power. More than this, the header pipe is essential for the proper venting of exhaust gasses into the exhaust system, through the catalytic converter and out of the tail pipe. Without the header pipes, proper environmental safeties would be circumvented. Driving an Infiniti was a smart choice, now keeping it in great shape is even smarter!

They are available for the following Infiniti QX4 years: 2003, 2002, 2001, 2000, 1999, 1998, 1997, 03, 02, 01, 00, 99, 98, 97. This part is also sometimes called Infiniti QX4 Muffer Pipe. We stock header pipe parts for most Infiniti models including G20.
