Constructed from mandrel-bent 304 stainless steel tubing, these headers provide exceptional strength, durability, and corrosion resistance for long-lasting performance. The optimized unequal-length tube design enhances exhaust scavenging while creating the iconic boxer rumble. Formed collectors reduce turbulence and improve exhaust velocity, while factory-style laser-cut flanges provide a secure, leak-free seal. Featuring 100% TIG-welded construction, the Twisted Steel Headers are designed for a direct-fit installation using factory exhaust locations with no cutting or modifications required—proudly engineered and manufactured in the USA.\nTwisted Steel Long Tube Header 304 Stainless Steel Subaru Impreza WRX\/STi\/Legacy 02-21 H4-2.0L (t)\/2.5L (t)\n\u003cul\u003e\n  \u003cli\u003eWorks with Factory Exhaust System with No Modifications Necessary\u003c\/li\u003e\n  \u003cli\u003eConstructed out of Mandrel-Bent 304 Stainless Steel Tubing\u003c\/li\u003e\n  \u003cli\u003eOptimized Tube Lengths for Improve Flow and Performance\u003c\/li\u003e\n  \u003cli\u003eLaser Cut Flanges are used for a Durable Leak-Free Seal\u003c\/li\u003e\n  \u003cli\u003e100% TIG-Welded for Strength and Durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eaFe POWER Twisted Steel Long Tube Headers are designed to improve exhaust flow, horsepower, torque, and throttle response on select Subaru Impreza WRX, STI, and Legacy models with 2.0L or 2.5L turbocharged engines.
