DESCRIPTION

Our take on the classic 4 to 1 Miata header! The most bang for your buck, with all the features you need in an all stainless steel header.

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. O2 sensor bung included after the merge.

Manual transmission only. EGR compatible.

Gasket included. Comes with a plug loosely installed in the oxygen sensor bung.

Note that adding any header results in an increase in the exhaust sound level on your Miata.

Note there is an INTENTIONAL small dent in one of the primary tubes for clearance to the steering rod.

Manual Transmission Only.
SORRY, WE CANNOT SHIP TO CALIFORNIA CUSTOMERS! CARB NOTICE: Not CARB approved (and therefore legal in California for off road use only). Note that there are states in addition to California that now follow the California model and require CARB compliance, please check the rules of your state before ordering, in some states this setup is legal only for race cars and may never be used on public highway. Sorry, we will not ship these to residents of California.

This header is a direct replacement for the factory 1999-2000 header on all Federal Miatas that do not have a catalyitic converter in the factory header. For Miatas that were originally sold in California which DO have a catalytic converter in the header, this header will fit those cars but you will need to relocate the oxygen sensors downstream to the catalytic converter located in the midpipe, and you will need our "Race Header O2 Wiring Kit" to accomplish that.

Brian's Application Notes: Year after year our top choice was the Racing Beat and year after year they ran out of stock because the batches of CAST flanges would be too warped to use and then they would be out of stock for months trying to get a good batch. We got tired of that, customers were tired of that, so we did our own that avoids the use of the problematic cast flanges and otherwise is similar for pipe size and length and all stainless construction. We think it is the best header you can get for the money and as a result our warranty is lifetime, which you will not get on ANY other choice!

RoadsterSport Miata Header

First off - I want to say that this header is beautifully made. The welds are great, the flanges are perfect, and the stainless steel seems like top quality. Quality is my main concern with any new part, and this header does not disappoint.

My issues we mainly with shipping/handling. I've ordered from GW before without issue so this was probably a fluke. The front end manifold flange was sticking through the side of the box when I received it, but it still seems perfectly straight. The 4th runner came with a pretty serious scuff/scratch on the front it. Because of how hard it has been to get a header this year, and how it was almost immediately backordered after I ordered it, I figured if I wanted to return it, it would be a long time before I got another one, so I just installed it as is. Now that the header has heat cycled a few times, it is less noticeable, but I will probably still cover it with a heat shield anyways.

This header, paired with the rest of my exhaust, is pretty loud. I have the 2.5" FM catted & resonated mid pipe, and the roadstersport4 muffler. It has a really nice tone at idle and lower RPMs, but during WOT it can get pretty "ricey" for lack of a better term. I don't have any experience with other Miata headers so I can't say if this is normal for all of them. The Civic-like sound was not present with the FM midpipe and RS4 muffler, before I added the header. It makes it a little harder to drive it around town without getting a lot of unwanted attention.

Overall - 7.5/10 stars.
