STM R35 GTR Stainless Race Y-Pipe

The STM GTR Race Y-Pipe boasts a streamlined, straight-through design, crafted entirely from T304 stainless steel and meticulously TIG welded in-house. Ideal for enhancing airflow during track sessions, this y-pipe is available with either a 3.5" flange for aftermarket exhausts or a 3" flange for stock cat-back systems.

This y-pipe stands as our top choice for a bolt-on race pipe, seamlessly fitting into stock locations and coming complete with all essential hardware and gaskets for a straightforward installation.

 Vehicle Fitment: 
2009-2021 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.
