Headers--2001-2005-Mazda Miata MX-5

RoadsterSport Miata Header (Good-Win-Racing) 01-05 . Only used for 1 week so basically brand new.
Manufactured entirely from 304-stainless steel with thick flanges that will not warp like other stamped or cast flanges. Large 1.7" primaries collecting to a 2.375" OD tube via a smooth 4:1 merge.
Now UPDATED to include TWO O2 sensor bungs: one right after the merge, for your primary O2 sensor, and a second bung further down by the outlet flange which you can use to add an auxiliary wideband sensor, or use it when you go to the dyno for the sensor that's hooked up to the dyno, etc. All without having to weld in an extra bung later.
Manual transmission only. EGR compatible.

What is a Scouted listing?

Scouted listings are our way of bringing you the fullest catalog of parts for sale. We hunt for parts from around the web and reshare them on Racebuilds. This is great for buyers because it means they get access to hard-to-find parts, and it's great for sellers because it means they get more exposure for their listings.

What happens when I purchase?

When you purchase a Scouted listing, we'll reach out to the seller on your behalf. We work with them to coordinate payment and shipping.

What happens if you can't get the part?

We sometimes can't complete the purchase request for a variety of reasons. Sellers may not respond, the part may have already been sold, or they might not be willing to ship. If we can't get the part, we'll cancel the purchase request and you won't get charged.

What is the estimated shipping cost?

We make a crude estimate of the shipping cost based on the price. Most of the time we're in the ballpark and can fulfill the purchase at the stated price. If the shipping cost is significantly higher, we'll reach out to you to see if you're still interested.

Am I charged immediately?

Nope! We only charge you when we have confirmed that the seller is willing to sell the part and ship it to you.

I see a payment authorization, what's up with that?

When a purchase is submitted, PayPal authorizes the payment. It's not a charge, but it does reserve the funds. This helps sellers know that you're serious about buying the part. If your offer is canceled for any reason, the authorization is usually canceled within 24 hours.

What if I change my mind?

Just let us know and we'll cancel the purchase request. You won't be charged.

Do you have the part in stock?

Since these are Scouted listings, we don't have the part in stock. They've been reshared from various communities around the web.

This is my part, can I claim it or remove it?

Yup! If you're the seller, just send us a message and we can either transfer the listing over to you or remove it. Up to you.

Are all Racebuilds listings Scouted listings?

Nope! Racebuilds main focus is providing a place for enthusiasts to list their parts for sale. Scouted listings are just a way for us to bring you additional parts that we think you'll like.
