Torque Solution Equal Length Header - Subaru WRX 94-14 / STI 94-21 / Liberty GT 05-09 / Forester XT 04-08

Application: Subaru WRX 1994-2014, WRX STI 1994-2021, Liberty GT 2005-2009, Outback XT 2008-2009, Forester XT 2004-2008
Part Type: Equal Length Header / Exhaust Manifold
Part Number: TS-SU-923-EL

The Torque Solution 2-bolt Equal Length Header is a direct replacement for the OEM STI header on EJ-powered Subarus, delivering increased flow and faster spool. It is built from 304 stainless steel tubing with 2.8mm wall thickness and a high-flow forged stainless 4-1 merge collector, fully TIG welded and back purged.

Designed to pair with a stock-location or aftermarket turbo setup that uses a 2-bolt up-pipe.

Independently dyno and track tested by Bader Built Racing on a stock-location DOS100 turbo: a 9.14 sec @ 154 mph pass on the strip, and on the dyno 733 whp / 629 wtq at 30 psi. In back-to-back testing against a competitor's header it gained 15 whp and 21 wtq at peak, up to 46 whp and 57 wtq through the midrange, and spooled a few hundred rpm earlier.
