ISR Performance EP (Straight Pipes) Dual Tip Exhaust - Nissan 240sx 89-94 (S13) - 4"

The ISR Performance EP straight pipe dual tip exhaust in the 4 inch tip version gives the 1989 to 1994 Nissan 240SX S13 a bolder rear view than the standard 3 inch tip EP. It uses the same 3 inch straight pipe layout, then finishes with a pair of 4 inch tips that fill the S13 bumper cutout.

What's in the box

• 4x bolts
• 4x nuts

EP means straight pipes

The EP series is ISR's race exhaust. There is no resonator and no muffler in the system, so the exhaust path is as open as it gets on an S13. That makes it a strong match for turbo cars that need to move a lot of exhaust, and it also makes it loud. Treat it as a track, drift or show piece rather than a quiet street exhaust.

3 inch versus 4 inch tips

Flow is identical between the two EP dual tip versions; the piping is 3 inch either way. The choice comes down to appearance. The 4 inch tips are the larger, more aggressive option and stand out more against the rear valance.

Fitment

Fits the 1989 to 1994 Nissan 240SX S13 and mates to a 3 inch 2 bolt flange at the downpipe or test pipe. An S14 version with 4 inch tips is also offered.

Installation

Two sections, two gaskets, four bolts. Assemble loosely, set the tips so they sit evenly in the bumper opening, then torque the flanges.
