Product Specifications
Catless Exhaust Downpipe Pair for 2000–2004 Porsche Boxster 986 2.7L and 3.2L
Built for the naturally aspirated 986 Boxster, this pair replaces the catalytic-converter pipe sections downstream of the headers. The catless layout offers a freer exhaust path for a 2000–2004 Boxster 2.7L or Boxster S 3.2L project intended for off-road or track use. Select the downpipes alone or the option that also includes exhaust headers, and check the connections on your car before ordering.

Key Features
- Catless pipe sections: Replace the factory primary catalytic-converter sections for an off-road exhaust build.
- Left and right pipes: Supply both sides of the Boxster's exhaust layout.
- Tri-bolt header flanges: Provide the upstream connection described for the original or compatible aftermarket headers; compare your flange before purchase.
- CNC-machined flanges: Provide accurately formed mating faces at the connections.
- TIG-welded stainless construction: The listed welded joints and stainless material address heat and corrosion exposure.
- Mirror-polished finish and shaped routing: Follow the listed underbody layout while providing a polished appearance.
The existing product description estimates 8–12 HP with an ECU tune and describes stronger response through 4,000–6,500 RPM when paired with headers and a cat-back exhaust. These are conditional estimates, not guaranteed results; the outcome depends on vehicle condition and the rest of the exhaust system. The original page also describes a more noticeable exhaust sound after removing the primary catalysts.
What Is Included
- Two catless downpipe pipes
- Six flange bolts and six flange nuts
- Two gaskets
Check Before Ordering
- Confirm your Boxster's year, engine, trim and exhaust configuration. The existing fitment tab describes 2000–2004 Base 2.7L and S 3.2L broadly; the year and trim combinations above follow the SKU fitment table.
- Compare the tri-bolt header flange, downstream connection, sensor ports and clearance with the parts on your car. Aftermarket header connections can differ. For help with flange details, email service@flasharkracing.com.
- Choose the header option deliberately: the “Exhaust Header” selection is a separate bundle SKU, FLES08323-ES08218; “No Header” is the downpipe pair SKU, FLES08323. Confirm the selected option and its contents at checkout.
- This catless part removes a catalytic-converter section. It is offered for off-road and track use only; check the rules that apply to your vehicle and location before purchase or installation. A check-engine light associated with catalyst monitoring may occur.
