ISR Performance GT Single Exhaust Nissan 240sx 95-98 S14

Built for the 1995 to 1998 Nissan 240SX S14, the ISR Performance GT single exhaust is a 3 inch catback that pairs a 3 inch mid pipe with a 3 inch muffler section and a single 4.5 inch tip. It is the S14 version of ISR's GT single and the pick for owners who want a straight path from the downpipe back with one large tip at the rear.

Why a non resonated mid pipe

The GT system skips the inline resonator. That leaves the muffler as the only sound control, which produces a louder, rawer note than ISR's resonated MB SE systems. If you are building a drift car, a weekend track car, or just like a 240 that announces itself, this is the one. If you commute in the car daily, consider the MB SE instead.

What's included

• 1x 3 inch mid pipe
• 1x 3 inch muffler section with 4.5 inch tip
• 2x 2 bolt 3 inch exhaust gaskets
• 4x bolts and 4x nuts

Fitment

Nissan 240SX S14, 1995 to 1998, both zenki and kouki body styles. Requires a 3 inch 2 bolt flange at the downpipe or test pipe. Not for the S13; that version is listed separately.

Performance notes

Full 3 inch piping suits SR20DET and turbo KA24 setups where the exhaust side needs to keep up with boost. On a stock KA it mainly adds sound and sheds some weight versus the factory system.

Fitting tips

Install both sections loosely, center the 4.5 inch tip in the bumper, then tighten the flanges and check the hangers for slack.
