Description
These catless race headers are crafted from 304-grade stainless steel with high-strength TIG welds, thick flanges, and tuned length runners. The primary external diameter is 45mm, collector diameter is 54mm. This part is deal for track use to increase performance, reduce heat in your engine bay, and prevent damage to the factory cats.
They fit all 987.2 Porsche Cayman and Boxster, from 2009-2012, base, S, R and Spyder models, 2.9L and 3.4L. We recommend the purchase of new OEM-style metal exhaust gaskets to install along with the headers which can be purchased as an add-on, or procure your own from your favorite replacement parts supplier.
- The headers will bolt right up to the OEM exhaust, any Top Gear exhaust, or any aftermarket exhaust with OEM fitment.
- Recently these headers have been shipping with 3/8″ hardware, rather than 5/16 or M8. You can either source some new 5/18 or M8 hardware from your local hardware store (6 high strength bolts + 6 nuts and 12 thick washers) or drill out your OEM exhaust flange holes to 3/8″. We recommend the 5/16″ hardware to be used with new OEM gaskets.
- These headers are not CARB certified, and may not be legal for road use in your area. These are sold as an off-road part.
- After the installation of this product, the emissions or check engine light might come on your dash. We partner with and sell Softronic tunes at a discount to anyone who purchases a Top Gear product, to maximize the power gains from the headers and get rid of the CEL.
- Due to the current administration’s decision to remove the de minimis exemption, Top Gear products will now be subject to a tariff as they are shipped from the UK. We have done as much as possible to reduce this cost and pass the savings onto you, so the value you receive means these are still the best option on the market.
- DHL will contact you to pay the tariff, which should be around $50, though if there are any adjustments to tariffs or fees this may change.
