Overview

It addresses flaws in the OEM header, which restricts exhaust flow and leads to power loss. This Tomei header eliminates these restrictions, particularly in the turbo side port, by utilizing a smooth merging collector made with the lost wax method.
Show original supplier description
Constructed using the lost wax method for its collector, the EXPREME manifold ensures a smooth merge of exhaust pipes, thereby eliminating flow restrictions. The OEM header's turboside port, often limited to 33mm, is a significant bottleneck that this Tomei upgrade resolves. Furthermore, the header features a stepless, rigid, and lightweight flange design. An innovative slider adjuster is incorporated, allowing users to extend the header to accommodate thicker headgaskets, providing greater flexibility for engine modifications. This system is specifically designed for the Subaru WRX models equipped with the FA20DIT and FB16DIT engines, fitting the 2015-2021 model years.
