Genuine Exhaust Manifold Gasket For Mazda MX-5 NC

Good Win Racing’s exhaust manifold for the Mazda MX-5 is packed with clever design improvements that not only increase power but ensure a long lifetime for the manifold, something you don’t see on cheaper manifolds. This entirely stainless steel header features a smooth 4 into 1 collector, huge 2″ primaries and winds down into a 2.5″ downpipe. One of the most unique things about the manifold is the extra thick, CNC machined stainless flange. This – unlike cast or stamped flanges – will not warp and helps to ensure a long-lasting, leak-free design.

The manifold features a single o2 sensor port, just after the collector. There are two o2 sensor ports after the collector of the manifold, both of the OEM sensors will fit but if installed on a standard ECU the ECU will throw an o2 error code. You can alter the stock ECU to avoid this by reflashing or you can put the second o2 sensor after the second cat for the ECU to not create a code.

This manifold deletes the first cat that is housed in the manifold of the Mazda MX-5, this gives a noticeable increase in exhaust note as this cat acts as a silencer.

The warranty is good for the period stated in the additional info tab from the date of purchase. Mileage warranties are for road use only and proof of mileage is required. Products must be installed by an independent experienced professional mechanic and the suspected defect must be present at the outset. The warranty does not cover damage caused by incorrect installation, failure to comply with the maintenance requirements of the vehicle, processing or otherwise changing the product, ordinary wear and tear, or any other external influences. Warranties are invalid if the product is used for racing, rallying, drifting, track days or any other form of motorsport or competition.

Making a warranty claim

Proof of purchase receipt showing the date of purchase, proof of mileage at installation, proof of current mileage and invoice of the work undertaken by an independent experienced professional mechanic must be supplied along with the returned products for a warranty claim to be considered. If your vehicle needs to be used whilst your warranty claim is considered replacement parts from the same manufacturer should be purchased through BOFI Racing. In the event of a successful warranty claim, we will refund the card that was originally used to purchase the replacement parts, in full or in part depending on the nature of the claim. BOFI Racing reserves the right to make full or partial compensation at its sole discretion depending on the condition and mileage use of the returned suspect parts. For example, if you have used the part for several thousand miles before a defect is noticed, only partial compensation may be offered.
