ISR Performance Series II - GT Single Rear Section Only - Nissan 240sx 89-94 (S13)

The Series II GT Single Rear Section is the modular axle-back component for S13 240SX owners on the Series II platform. Round-muffler single-tip rear that drops onto your existing Series II S13 modular mid without replacing the rest of the catback.

What It Does

Standalone rear axle-back section of the Series II GT Single exhaust. The 5" round muffler with 4.5" extended tip gives a balanced single-exit look, more refined than the EP Single's pie-cut turn-down. The Series II architecture is built so rear sections interchange across the Series II S13 family, letting you swap between GT Single, EP Single, and EP Dual rears without buying a new exhaust.

Fitment

Rear axle-back section only. Not a complete exhaust system. Works exclusively with the ISR Performance Series II S13 modular mid section. Will not work with original (non-Series II) ISR S13 exhausts, OEM exhaust, or any other manufacturer's catback. Designed for the Nissan 240SX 1989-1994 (S13 chassis).

What's in the Box

• 1x GT Single rear axle-back section
• 1x gasket and hardware pack
