Cat-Back Exhaust for the 2000–2009 Honda S2000 (AP1/AP2)
Designed for the 2000–2009 Honda S2000, this Flashark cat-back system covers both the AP1 (2.0L F20C) and AP2 (2.2L F22C1) generations and replaces the factory exhaust path from the catalytic converter back. It is built around 2.5 in mandrel-bent T-304 stainless steel piping, CNC-machined flanges, and a pair of 115 mm N1-style tips, with a mirror-polished finish across the system.
Flashark catback exhaust systems are made from stainless steel with a fully polished surface, CNC-machined flanges, and mandrel bends. This S2000 system follows the same straight-through layout with dual N1-style tips that mirror the car's factory dual-outlet rear.
Fitment
This cat-back exhaust is made for the two-door Honda S2000 coupe fitted with the factory AP1 or AP2 chassis and the F20/F22 series DOHC VTEC inline-four engines. Confirm your vehicle matches the compatibility table below before ordering.

Key Features
- T-304 stainless steel construction: The page lists the system's material as T-304 stainless steel with a mirror-polished surface, a corrosion-resistant grade commonly used for exhaust components exposed to heat, moisture, and road conditions.
- Mandrel-bent piping: The tubing is specified with computerized mandrel bends, which keep the inner diameter consistent through each bend instead of pinching the cross-section.
- CNC-machined flanges with TIG welds: Flanges are CNC machined and TIG welded at the joints, giving the system clean connection points for the install.
- 2.5 in main piping: The main path is sized at 2.5 in, matched to this S2000 cat-back layout; if you are combining it with other exhaust changes, confirm the full setup against your vehicle before ordering.
- Dual 115 mm N1-style tips: The system uses dual N1-style tips at 115 mm, following the S2000's factory dual-outlet rear layout so the finished look stays symmetrical.
- Bolt-on cat-back installation: The system mounts behind the factory catalytic converter with direct bolt-on fitment, so the converter and its sensors stay in place; no installation instruction sheet is included, and professional installation is recommended.
Check Before Ordering
- Confirm your vehicle is a 2000–2009 Honda S2000 with the 2-door coupe body style, AP1/AP2 factory chassis, and F20C/F22C1 DOHC VTEC inline-4 engine listed in the Fitment table.
- If the exhaust ahead of the catalytic converter (header, downpipe, test pipe, or catalytic converter) has been modified, the mounting point for this cat-back may differ from the factory outlet; verify your current exhaust layout before ordering.
- A detailed package contents sheet is not published for this system. If you need the gasket and hardware breakdown before purchase, contact our support team to confirm what ships with the system.
- No installation instruction sheet is included with this system. Professional installation is recommended to align the dual tips with the rear bumper openings.
- If the rear bumper or exhaust outlets have been modified from the factory layout, confirm that dual 115 mm tips will fit your openings.

2000–2009 Honda S2000 Catback Exhaust FAQs
Q1: Will this exhaust fit both AP1 and AP2 Honda S2000 models?
A1: Yes. The system is made for the 2000–2009 Honda S2000 in both generations — AP1 with the 2.0L F20C and AP2 with the 2.2L F22C1 DOHC VTEC inline-4 engines — on the 2-door coupe body style with AP1/AP2 factory chassis. If your car matches those factory specs, this cat-back is the intended fit; heavily modified chassis or drivetrain setups should be checked against the Fitment table first.
Q2: Where does the cat-back system start and end?
A2: It is a cat-back system, meaning it installs from the outlet of the factory catalytic converter toward the rear of the car, and it keeps the converter in place. Because the mounting point is the factory converter outlet, verify that the exhaust ahead of the converter has not been changed before ordering.
Q3: What is the main piping diameter?
A3: The main piping is 2.5 in, as listed in the Specifications section. The measurement is not published as an outside or inside diameter figure, so if you need an exact dimension for your existing setup, confirm the measurement point with our support team before purchase.
Q4: What materials and finish are used?
A4: The system is built from T-304 stainless steel with a mirror-polished surface, and the flanges are CNC machined and TIG welded. Those are the core construction details specified for this S2000 system.
Q5: What tips come on this system?
A5: The system is fitted with dual N1-style tips at 115 mm, designed to follow the S2000's factory dual-outlet rear layout. If the rear bumper or exhaust outlets have been modified from the factory arrangement, confirm the tip openings will match before you order.
Q6: Is installation bolt-on, and are instructions included?
A6: The product page specifies direct bolt-on fitment with no modifications required, installing behind the factory catalytic converter. No installation instruction sheet is included with the system, and professional installation is recommended so the 115 mm tips are aligned correctly with the bumper openings.
Q7: Will this system affect my factory emissions equipment or trigger a check engine light?
A7: As a cat-back system, it installs behind the factory catalytic converter and does not relocate the converter or its sensors. A check-engine light is usually tied to converter or sensor faults, so the risk is low with the factory emissions equipment left in place — but if your vehicle already has other exhaust modifications or an existing fault, diagnose that condition separately rather than assuming this install is the cause.
Q8: Are gaskets and connecting hardware included?
A8: A separate package contents list is not published for this system, so the exact gaskets and hardware that ship with it are not confirmed here. Contact our support team before ordering if you need the hardware breakdown to prepare for installation.
Q9: Is there a sound clip or dB measurement available?
A9: No audio clip or decibel test is currently published for this S2000 system. Exhaust sound is subjective and depends on the rest of the vehicle's setup, so if you are choosing based on tone, ask our support team whether recorded audio for this system is available.
Q10: Can I install this if my car already has a modified header or downpipe?
A10: This cat-back is designed to mount at the factory catalytic converter outlet. If the header, downpipe, test pipe, or converter section has been replaced or altered, the mounting location may sit at a different position or angle than the factory outlet. Review your current exhaust layout and confirm fitment with our support team before ordering.
Q11: How do I keep the mirror-polished tips and piping looking clean?
A11: Wash the tips and visible piping regularly with standard car-wash soap and water to remove carbon and road grime. For a deeper clean, apply a non-abrasive stainless steel polish periodically to the visible surfaces. Let the exhaust cool fully before cleaning.
