The P&L Motorsports Subaru WRX/STI EJ20 & EJ25 Exhaust Manifold Header is constructed of fully T304 stainless steel schedule 10 piping and custom CNC cut T304 stainless flanges. Our unique design effectively minimizes back pressure to increase horsepower and turbo output. Incorporating a 4-into-1 merge design, this system features an equal length runner arrangement in order to help reduce the amount of exhaust gas backpressure, while still allowing for excellent sound output and tone. An equal length design was chosen due to the increased efficiency over the traditional un-equal length stock manifold. Designed, tested, and fabricated in-house from start to finish, this header will increase horsepower output, when combined with accompanying ECU calibration. All P&L fabricated exhaust components come standard with our 3-year limited warranty.

  • 304 Stainless Steel Schedule 10 Thickness Piping

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.

    Donald Wojnar

  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.

    Adam Cranston

  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.

    Bryce Budd

  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.

    William Brunell

  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
