TR - Twin Scroll Equal Length Header/ Up-Pipe Combo

New Old Stock. This header combo was test fitted on a build but never ran. Literally brand new setup! Will also include new gaskets for Install.

The Tomioka Racing 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.
