The Tomioka Racing Gen 2 Twin Scroll Equal Length Exhaust Manifold is designed to elevate Subaru performance with its larger 43mm outer diameter, a significant upgrade from the previous generation's 38mm.

This increase in size boosts exhaust flow volume by 28.5%, resulting in improved flow dynamics and enhanced turbo performance. Constructed from high-quality SUS304 stainless steel, the manifold is built to withstand extreme conditions while resisting corrosion. 

Its equal-length runner design helps balance exhaust pulses, leading to quicker turbo spool times and smooth power delivery across the RPM range, making it ideal for both street and track use.

This exhaust manifold is precision-engineered for perfect fitment on 02-14 Subaru WRX, 04-21 Subaru STI, 05-09 Subaru Legacy GT, and 04-08 Subaru Forester XT models, requiring no modifications for installation.

It comes with a complete installation package, including an exhaust manifold, up pipe, turbo gaskets, exhaust wrap, and a full hardware kit for easy setup. The lost wax finish and 3-1 connectors ensure optimal exhaust flow, secure fitment, and reliable performance, making it a must-have for Subaru enthusiasts seeking both durability and performance gains.
