ISR Performance Single GT Exhaust - Nissan 240sx 89-94

Our Single GT exhaust for the S13 240SX. Cat-back stainless system with 3" piping and a 4.5" polished tip, tuned for the deep, aggressive tone the Single GT family is known for across the rest of the Nissan lineup. Now bringing that same character to the S-chassis where the family started.

What It Does

Replaces the factory cat-back with a precision TIG-welded stainless system that opens up airflow for both naturally aspirated KA and SR-swapped builds. The 3" piping and 4.5" tip combination delivers strong mid-to-high-end power gains with the kind of tone that makes the S13 sound like the drift car it wants to be. Includes a removable silencer for sound-limited days at the track.

Fitment

Fits the Nissan 240SX (S13), 1989 to 1994. Works with KA24DE, KA24E, and SR20DET swap applications using the factory 240SX exhaust routing.
