The STM R35 GTR y-pipe features a free-flowing, straight-through design, fully T304 stainless construction and TIG welded in-house. If you're looking to free up air flow for track days, this is exactly what you need. Available with a 3.5" flange to bolt to aftermarket exhausts or a 3" flange for the stock cat-back.

This is our pipe of choice for a bolt-on race pipe! This piece fits to stock locations and and includes all necessary hardware and gaskets for a clean and simple install.

Vehicle Fitment:
2009-2025 Nissan R35 GT-R

Options:
The STM Y-Pipe features a 3.5" primary tube to bolt up to a 3.5" aftermarket cat-back exhaust or we offer the option of a smooth transition to fit stock or aftermarket 3" cat-back exhausts.

Results:
Tested with a stock cat-back we saw gains of +18 TQ and +8 HP without changing the tune. Bigger gains can be expected with aftermarket cat-back and a tune.

Features:
• Hand built and precision TIG welded in the USA

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.
