Key Features
- Complete Cat-Back Coverage: This kit replaces the exhaust from the factory catalytic converter back — piping, single muffler, resonator, and tip — as one matched system.
- 3 in OD Main Piping: The main tubing measures 3 inches in outside diameter, so you know the exact pipe size you are ordering and what you are replacing.
- Mandrel-Bent Tubing: The piping is mandrel-bent, meaning the tube bore is not squeezed at the curves the way crush-bent pipe can be.
- Single Muffler With Resonator: The layout uses one muffler and one resonator, which is what you are buying — a single-exit cat-back, not a muffler-only or axle-back section.
- Polished 201 Stainless Steel: Piping and muffler are built from 201 stainless steel with a polished surface, and the tip is polished to match the system finish.
- Single Polished 4.5 in Tip, Single-Side Exit: The system finishes with one polished 4.5-inch tip exiting on a single side, so you know the finished look before you order.
- Bolt-On Installation With Hardware Included: No cutting is required, and gaskets, bolts, and nuts are included for installation.
All main sections are 201 stainless steel with a polished finish, and the piping is mandrel-bent throughout the system. The sections bolt together with the included gaskets, bolts, and nuts, and the system mounts in place of the original rear exhaust sections with no cutting required. The factory catalytic converter stays in place.

1989–1994 Nissan 240SX (S13) Catback Exhaust FAQs
Q1: Which Nissan 240SX models does this cat-back exhaust fit?
A1: This system is built for the 1989–1994 Nissan 240SX (S13) with the 2.4L four-cylinder engine. It covers the two-door convertible, coupe, and hatchback body styles listed in the fitment chart. Always confirm your vehicle’s year, engine, and body configuration before ordering.
Q2: What does this kit replace on the vehicle?
A2: It is a cat-back system, so it replaces the exhaust from behind the factory catalytic converter to the rear tip — the main piping, muffler, resonator, and tip. The factory catalytic converter stays in place.
Q3: Is this a single-exit or dual-exit exhaust?
A3: It is a single-exit system. The kit includes one polished 4.5-inch tip that exits on a single side of the rear. If you need a dual-tip or dual-exit layout, this kit is not the match.
Q4: What is the pipe size on this 240SX exhaust?
A4: The main piping is 3 inches in outside diameter (OD) and is mandrel-bent through the system, so the tube bore stays consistent through the bends.
Q5: What material is this exhaust made from?
A5: The main piping and muffler are made from 201 stainless steel with a polished surface, and the tip is polished to match. The specifications table on this page lists the full material and finish details.
Q6: Does the exhaust come with mounting hardware?
A6: Yes. Gaskets, bolts, and nuts are included with the kit for installation. The system mounts using the factory hanger positions.
Q7: Is cutting or welding required to install this exhaust?
A7: No. This is a bolt-on system and no cutting is required. If you are not comfortable working under the vehicle, have the system installed by a qualified shop.
Q8: Can I install this cat-back at home?
A8: An experienced DIYer with basic hand tools, jack stands, and a way to support the old exhaust while removing it can handle this type of install. For best tip alignment and properly sealed joints, professional installation is a reasonable choice.
Q9: Is this 240SX exhaust street legal?
A9: This product is designated for racing and off-road use. Exhaust noise and emissions rules vary by state and region, so check your local laws before using the vehicle on public roads.
Q10: Will this fit a 1995–1998 Nissan 240SX?
A10: No. This system is listed only for the 1989–1994 Nissan 240SX. The 1995–1998 model years are not covered by this kit.
Q11: Does this system work with the factory catalytic converter?
A11: Yes. The kit is designed as a cat-back system and bolts to the outlet of the factory catalytic converter, which is retained. The converter and its surrounding components are not part of what this kit replaces.
Q12: What does the muffler and resonator layout look like?
A12: The system uses one muffler and includes one resonator as part of the single-exit layout. If you have questions about how this compares with the configuration on your car, contact us with your vehicle details before ordering.
