ISR Performance GT Single Exhaust Nissan 240sx 89-94 S13

The ISR Performance GT single exhaust for the 1989 to 1994 Nissan 240SX S13 is a 3 inch catback made up of a 3 inch mid pipe and a 3 inch muffler section exiting through a single 4.5 inch tip. It is a no nonsense system aimed at S13 owners who want a large diameter exhaust and a big single tip without the extra bulk of a dual exit setup.

GT versus MB SE

ISR offers a few 3 inch systems for the S13. The GT uses a straight mid pipe rather than the resonated front pipe found on the MB SE, so it has a louder, more aggressive tone and a more direct exhaust path. The muffler at the rear keeps it from being a full straight pipe, but expect more volume than the MB SE line.

Fitment

Nissan 240SX S13, 1989 to 1994 model years. The GT single is also made for the 95-98 S14. Connects to a 3 inch 2 bolt flange from a downpipe or test pipe.

Who it is for

SR20DET and turbo KA builds that want the exhaust side opened up all the way, and drift or track S13s where sound is part of the point. The 4.5 inch tip gives the rear a bold look in the stock bumper cutout.

Install

Assemble loosely with the included gaskets and hardware, set the tip, then torque the 2 bolt flanges.
