Rennkraft Modular Headers with Catalytic Converters
Fabspeed's patented RENNKRAFT modular headers for the Porsche 987.2 Boxster/Cayman, built with a quick-release V-band connector so you can swap between German German manufacturer of the high-flow catalytic converters Fabspeed fits in its sport cat products. 200-cell catalytic converters and cat-bypass straight pipes without replacing the whole header. Fabspeed's testing showed gains of 25 hp and 20 ft-lbs of torque, saving 2 lbs with the sport cats fitted or 7 lbs with the cat-bypass section. They're CNC mandrel-bent T304L stainless steel, made in-house, and designed from 3D scans of the factory headers for a precise bolt-on fit; with the HJS cats fitted, Fabspeed guarantees no catalyst-related check engine light. Fits all Porsche 987.2 Boxster/Cayman vehicles worldwide from 2009 to 2012, including Cayman R and Boxster Spyder.
Frequently asked
Does the Rennkraft Modular Headers with Catalytic Converters fit my Cayman?
This listing is specific to the Porsche Cayman (987.2). Exact fitment for your year, trim and options is confirmed on your free consult before anything is ordered.
What does the price include?
The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.
How long until it arrives?
Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.
What's the benefit of the V-band connector?
It lets you quickly swap between the HJS catalytic converters and cat-bypass straight pipes without replacing the whole header, useful for switching to bypass pipes for track events and back for street driving.
Will the sport cat version trigger a check engine light?
No, Fabspeed guarantees no catalyst-related check engine light with the HJS sport cats fitted.
Do I need an ECU tune with these?
No, Fabspeed says no ECU tune is required.
Which option should I choose?
Choose Sport Cats for a street-legal setup with no check engine light, guaranteed by Fabspeed. Choose Cat Bypass Pipes for maximum flow on track, off-road use only. Choose Sport Cat + Cat Bypass Pipes to get both sections, so you can swap the V-band-mounted cat section out for track days and back again for the street.
Who installs it?
Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.
Is it covered by warranty?
Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
Can I just buy this outright, or do I need to talk to someone first?
