Replacement High Flow Up-Pipe Kit

The undersized OEM up-pipes are not corrosion resistant and introduce restrictions to the system, impairing turbo charger efficiency and increasing pumping loss. The PPE High-Flow Up-Pipes tackled these issues with a stainless-steel construction and a non-restrictive design. By enlarging the OEM bottle neck and eliminating the tight bends, PPE up-pipes can increase exhaust airflow by up to 46%, allowing for a smooth exhaust process.

These up-pipes are a direct bolt-on to your OEM exhaust manifolds. Replacement up-pipe gaskets are also included for a hassle-free installation.
