Product Specifications

1995–1998 Nissan 240SX S14 2.4L Cat-Back Exhaust System (4" Muffler Tip)

The Flashark 1995–1998 Nissan 240SX S14 catback exhaust is engineered as a direct bolt-on replacement for the factory mid-muffler and tail section on 2.4L KA24DE coupes. It runs a single 3 in OD stainless steel piping path through one muffler and one resonator, and exits through a single 4 in polished muffler tip on the driver-side rear. The kit bolts to the existing catalytic converter with no modifications, and ships with the gaskets, bolts, and nuts needed for installation.

The system is built for the 1995–1998 240SX S14 chassis (Silvia SE / LE body) with the 2.4L KA24DE engine. The piping routing, hanger placements, and exit position are matched to the S14 chassis, so it drops in behind the factory catalytic converter without custom fabrication. If you are fitting a 1989–1994 S13 chassis, see "Check Before Ordering" below before purchasing.

Key Features

  • Direct Bolt-On Fitment: The system mounts to the factory catalytic converter using a 2-bolt flange, so installation requires no cutting, no welding, and no modification to the existing exhaust path.
  • Single 3 in OD Piping: A single 3 in OD pipe runs from the cat-back flange to the rear, paired with one resonator and one muffler, replacing the factory mid-pipe and tail section in one kit.
  • Single 4 in Polished Muffler Tip: The system exits through a single driver-side rear polished tip sized at 4 in visible outlet (4.5 in full OD) — a large-diameter outlet for a wider exit than the factory tip.
  • Stainless Steel Construction: The piping, muffler, and resonator are built from 201 stainless steel with a polished silver finish, paired with CNC-machined flanges for the connection points.
  • Hardware Included: Gaskets, bolts, and nuts ship with the kit, so installation can be completed with the supplied hardware without sourcing additional fasteners.
  • Designed for S14 Chassis: Piping routing and hanger positions are matched to the 1995–1998 240SX S14 chassis (Silvia SE / LE), so the kit drops in behind the factory catalytic converter without custom fabrication.

What's Included and Not Included

Included in this kit:

  • Cat-back exhaust assembly (piping, resonator, muffler, single 4 in polished tip)
  • Mounting gaskets
  • Mounting bolts and nuts

Not included (must be reused / sourced separately):

  • Factory catalytic converter — must remain on the vehicle; this kit bolts downstream of the cat
  • Factory O2 sensors and oxygen sensor wiring — must be reused; the catback does not interact with O2 sensors
  • Exhaust hangers / rubber mounts — must be reused from the factory if worn replacements are needed

Check Before Ordering

  • Chassis fitment: This kit is for the 1995–1998 Nissan 240SX S14 (Silvia SE / LE) only. It is not a direct bolt-on for the 1989–1994 S13 chassis, which uses different mounting points and exhaust routing.
  • Catalytic converter required: The factory catalytic converter must remain installed on the vehicle. This is a cat-back system, not a cat-back-and-front-pipe or turbo-back system.
  • Designated use: This kit is designated for Racing / Off-Road use. Check your local emissions and street-legality rules before installing on a public-road vehicle. Federal, state, and local emissions compliance is not certified.
  • Body style: Confirmed for the factory-equipped two-door coupe body. Convertible, hatchback, or other body variants of the S14 chassis are not confirmed.
  • Engine: 2.4L KA24DE inline-4 only. The SR20DET swap or other engine conversions are not confirmed and may require additional adapters or modifications.
