Tomei Expreme Unequal Length Exhaust Manifold

Tomei knew the importance of keeping that signature Subie rumble with an UEL manifold, but also wanted to improve over the stock manifold. To accomplish this, they have gone away from the cast material to a SUS304 Stainless Steel for the piping and flanges. This change decreases weight and is also rust proof. Another change from the stock manifold was the merge collector, where it went from a 4-2-1 design to a 4-1. This increases the efficiency of the exhaust flow, which is continued in the oversized flange and up pipe.

 

Simple Install

Installing the manifold and up pipe is a breeze as it includes all hardware, gaskets and exhaust wrap. The exhaust wrap is especially beneficial to keep the heat inside the manifold and transferred to the turbo. It will also contribute to lower under hood, and oil temperatures.
