aFe Twisted Steel Down Pipe 409SS w/ Cat 16-17 Toyota Tacoma V6-3.5L spo-default Optimized Tube Lengths: Tube lengths

Optimized Tube Lengths: Tube lengths are optimized for true pulse control technology which improves flow and performance

The serrated/helix design (US PAT 07055513) creates turbulence in the intake manifold and increases air pressure in the combustion chamber for better performance

Anyone can make a stiff sway bars

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
