Berk Technology 2.5″ Test Pipe – Honda S2000 (2000‑2009)
Free up horsepower, ditch the cat, keep the dash clean. This Berk 63.5 mm (2.5″) stainless test pipe replaces the factory catalytic converter, cuts weight, and includes a built‑in O₂ spacer to help prevent check‑engine lights—95 % success on 2000‑2005 AP1 models.
Key Features
- Large 63.5 mm bore – maximises exhaust flow for NA or boosted builds.
- Full 304 stainless – corrosion‑proof tubing, flanges & welds.
- Integrated CEL fixer – mechanical O₂ spacer reduces MILs (less effective on 2006‑2007 drive‑by‑wire S2000s).
- Bolt‑on fit – pre‑drilled flanges match OE studs; no cutting or welding.
- Includes gaskets & hardware – ready for a driveway install.
What’s in the Box
- 1 × 2.5″ stainless test pipe with welded O₂ spacer
- 1 × Exhaust gasket
- Mounting bolts & nuts set
Vehicle Fitment
Year | Chassis | Notes |
---|---|---|
2000‑2005 | AP1 | 95 % CEL‑free |
2006‑2007 | AP2 (DBW) | Higher CEL incidence |
2008‑2009 | AP2 | Same fit; tune or spacer may be needed |
Installation Notes
Direct bolt‑up between the header and mid‑pipe. Soak factory bolts in penetrating oil for easier removal. Average install time: 45 minutes with basic hand tools.
OFF‑ROAD USE ONLY. Not legal for use on public roads or highways. Verify local regulations before purchase and installation.
FAQ
Will I need an ECU tune?
A tune is optional but recommended to maximise gains and eliminate any remaining CEL on DBW models.
How loud will it be?
Expect a noticeably louder exhaust note and quicker throttle response; volume depends on your muffler setup.
Does it reuse stock O₂ sensors?
Yes, the primary sensor remains in the header; the secondary sensor threads into the welded spacer on the test pipe.
