The ISR Performance Single GT Exhaust is a catback exhaust system for the 1995-1998 Nissan 240SX (S14). TIG welded stainless steel with 3 inch piping, a 4.5 inch polished muffler tip, and an included silencer for tone adjustability. No mid-section resonator, which gives it a louder, more aggressive character than resonated catbacks.
What It Does
Catback exhaust replaces the entire exhaust system from the cat back to the tip. The 3 inch piping flows enough for serious power builds (SR20DET, KA24DE-T, or full engine swaps), while the muffler keeps the tone deep and aggressive rather than uncapped. The included silencer lets you tone down volume when needed without removing the exhaust, which is useful for noise-restricted track days or neighbors who would rather not hear you at 6 AM.
Critical Spec Note
The S14 single GT exhaust does NOT include a mid-section resonator. This is a deliberate design choice for a more aggressive tone, but if you prefer a more refined character with less highway drone, look at the Series II resonated catback line instead.
