1988-1991 Honda CRX 1.5L 1.6L Catback Exhaust System
This bolt-on catback system is built for the 1988-1991 Honda CRX with the 1.5L D15B2 SOHC inline-four (ED8 factory chassis). It installs behind the factory catalytic converter as a direct bolt-on rear exhaust section, with no cutting or modification listed for fitment. Two muffler tip versions are offered on this page — a 4 in rolled tip and a 4.5 in burnt tip — so you can choose the rear finish that suits the car.
The system is made from stainless steel with a mirror-polished surface. Main piping is 3 in with mandrel bends, flanges are CNC-machined, and a detachable double-layer silencer is included as part of the layout. Both tip versions share the same piping and silencer arrangement; the difference is the tip size and finish, shown separately in the specifications below with each variant's SKU.

Key Features
- Bolt-On Catback Replacement: The system installs directly behind the factory catalytic converter as the rear exhaust section, so you know before ordering that it is a rear-section kit rather than a header, downpipe, or converter product.
- 3 In Mandrel-Bent Main Tubing: Main piping is 3 in with mandrel bends, which keeps the tube diameter consistent through each curve; you know the exact pipe size going in and can judge it against the rest of your exhaust setup.
- Detachable Double-Layer Silencer: The included silencer is a double-layer unit that can be detached, giving you the choice at installation to run the system with that silencing layer in place or to leave it off.
- CNC-Machined Flanges: The connection flanges are CNC-machined, which supports the bolt-on fitment by keeping the joining faces accurately aligned at each connection point.
- Mirror-Polished Stainless Steel: The system is made from stainless steel with a mirror-polished surface, so the material and the finished look of the exhaust are known before you buy.
- 4 In Rolled Flat Tip: The default variant finishes with a 4 in rolled flat tip; a second variant on this page offers a larger 4.5 in burnt tip instead, and each is listed separately in the specifications so the choice is explicit at the SKU level.
Check Before Ordering
- Confirm your engine and chassis: this system is listed only for the 1990-1991 Honda CRX 1.5L (D15B2 SOHC inline-four, ED8 chassis, 2-door/3-door hatchback). CRX models with the 1.6L Si engine or any other non-1.5L engine are not compatible.
- Choose your tip variant: this product page has two versions — the 4 in rolled tip and the 4.5 in burnt tip. Select the one you want before adding to cart.
- Understand the system scope: this is a catback kit for the section behind the factory catalytic converter. It does not include a header, downpipe, or catalytic converter, and the factory converter remains in place.
- Plan for installation: the vehicle needs to be raised to reach the exhaust connections and hangers. On a 30-year-old chassis, allow extra time for corroded fasteners and consider replacing worn exhaust hangers while the system is off.

Fitment & Compatibility
1990-1991 Honda CRX 1.5L Catback Exhaust FAQs
Q1: Will this catback exhaust fit my 1990 or 1991 Honda CRX?
A1: Yes — if your car matches the fitment table above. The system is confirmed for the 1990-1991 Honda CRX with the 1.5L D15B2 SOHC inline-four, ED8 factory chassis, in the 2-door/3-door hatchback body style. CRX models with other engines, such as the 1.6L Si, do not fit this system. Check your engine code before ordering.
Q2: Which tip option should I choose — the 4 in rolled or the 4.5 in burnt?
A2: Both versions share the same catback piping and silencer layout; the difference is the tip size and finish at the rear of the system. The 4 in rolled tip gives a rolled flat outlet, while the 4.5 in burnt tip is larger with a burnt finish. Pick the one that matches the rear look you want — each variant is listed separately in the specifications with its own SKU.
Q3: Does this exhaust system replace the catalytic converter?
A3: No. This is a catback system, which means it is designed to install behind your factory catalytic converter. The converter and the front exhaust section stay in place; the kit covers the rear exhaust path.
Q4: Does installation require cutting or welding?
A4: No. The product is listed as a direct bolt-on with no modification needed, so no cutting or welding is expected for fitment. You will need to raise the vehicle to reach the exhaust hangers and flange connections. On an older car, heavily corroded hardware usually responds well to penetrating oil and patience.
Q5: What are the exact pipe and tip dimensions?
A5: Main piping is 3 in with mandrel bends. For the 4 in rolled tip version, the muffler inlet is listed at 2.250 in and the tip at 4 in. The 4.5 in burnt tip version lists a 4.5 in tip. The two specification tables above show the variant-level detail.
Q6: What material is the system made from and how is it finished?
A6: The system is stainless steel with a mirror-polished surface. It uses CNC-machined flanges and mandrel-bent 3 in main piping, with a detachable double-layer silencer as part of the layout.
Q7: Does the system include a silencer, and can it be removed?
A7: Yes. A detachable double-layer silencer is part of the system. Because it is detachable, you can install it with the silencing layer in place or leave that layer off during installation. We do not publish decibel ratings or tone guarantees for this kit — treat the silencer as an option you control at install time.
Q8: Will this fit a CRX Si or another non-1.5L model?
A8: No. Fitment is limited to the 1.5L engine version of the 1990-1991 Honda CRX. CRX Si models use the 1.6L engine and are not compatible with this system. If your CRX is a 1.5L model with a different engine code than D15B2, confirm the code with us before ordering.
Q9: Do I need a tune or will this cause a check-engine light?
A9: This is a catback system: it installs behind the factory catalytic converter and does not replace or relocate the converter or front exhaust hardware. We do not publish tuning requirements or check-engine-light guarantees for this kit. If you are also modifying other exhaust or engine parts, confirm the full setup with your tuner or contact us before ordering.
Q10: Is the rolled edge on the 4 in tip purely cosmetic?
A10: The rolled treatment is primarily a styling detail: it gives the 4 in outlet a clean rolled rim with no sharp edge and keeps the mirror-polished theme of the system. If you prefer a different rear look, the second variant on this page uses a larger 4.5 in burnt tip instead.
Q11: What do I need to check before ordering?
A11: Confirm that your CRX is a 1990-1991 1.5L model with the D15B2 engine (ED8 chassis), choose the tip variant you want, and remember that this kit covers the catback section only — the factory catalytic converter, header, and downpipe are not included or replaced. Contact us with your vehicle details if anything is unclear.
Q12: Can I install this exhaust myself?
A12: Because the system is listed as direct bolt-on with no modification needed, it can be installed at home with the car raised on jack stands or a lift using basic hand tools. On a 30-year-old chassis, allow extra time for rusted exhaust hardware and consider replacing worn hangers while you are under the car. Professional installation is always a safe option if you prefer.
