STM R35 GTR Stainless Race Y-Pipe (Not for Street Use)

STM Tuned Inc.



We price match!

The STM GTR Race 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" 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:
2009-2021 Nissan R35 GT-R

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.

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.
