ISR Performance Single GT Exhaust - Nissan 370Z

The ISR Performance Single GT Exhaust for the 370Z is the polished-tip variant of our 370Z single-exit catback. 3" mandrel-bent stainless, brushed finish, and a 4.5" polished muffler tip with that deep aggressive note the VQ37VHR deserves. Pair it with our IS-Z34-Y Y-pipe for a complete catback setup, or grab the IS-Y-GT-Z34 combo package for 5% off versus buying them separately.

What It Does

Y-pipe back single-exit system. TIG welded stainless construction, brushed finish, and a mid section routed with a slight hump for W brace clearance. The single-pipe layout flows well for both NA and forced induction, so it works whether you're staying on the factory VQ37VHR or chasing more power. If you'd rather have a burnt blue tip for a darker look, the IS-GT-370Z-BT is the same exhaust with that finish.

Fitment

Nissan 370Z only. Will not fit the G37 Coupe (which uses our IS-GT-G37C single GT, despite sharing the IS-Z34-Y Y-pipe). Pairs with the IS-Z34-Y Y-pipe; do not use the IS-Z33-Y, which is for the 350Z and G35 3.5L.
