Twisted Steel™ 409 SS Exhaust Headers by aFe®. Primary Tubing Diameter: 1.625". The new Twisted Steel performance header from aFe Power is redefining the header industry with the new pulse control technology. aFe engineers have designed this header using optimum tube lengths and mitered collectors for maximum flow and velocity for power delivery across the entire power band.
|Primary Diameter: 1.625"|
|Series: Twisted Steel™|
- Optimized Tube Lengths Improve Flow and Performance
- 100% hand MIG-welded construction ensures optimal strength and durability
- Heavy duty gauge steel mandrel-bent tubing for unrestricted flow
- High quality 3/8" thick flanges are used for a complete 360 degree sealing surface
- Retains factory sensors
These headers are 100% TIG-welded and constructed of near equal length mandrel-bent, 16-gauge 304 stainless steel tubing with thick flanges to ensure a leak free seal. The smooth curves and increased diameter of this header helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability. The headers includes all components for a hassle-free installation with no modifications necessary.
This system is a direct bolt-on installation which requires no cutting or drilling to provide a hassle-free installation. Thick 1-piece flanges and OE-style gaskets are used to prevent warpage to ensure a leak-free seal over the life of the vehicle. Tube lengths are optimized for true pulse control technology which improves flow and performance. aFe has designed the performance connection pipes retain all your factory sensors for a hassle free installation. These connection pipes are a direct bolt-on installation which requires no cutting or drilling to provide a hassle-free installation. The performance connection pipes are constructed of durable 3" CNC mandrel bent, stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking.
Mitered collectors not only extend the tube lengths and decrease turbulence, but provide optimal exhaust scavenging. The result is increased horsepower, torque and improved throttle response.
