Racing Beat Miata Header
Our favorite Miata header for normally aspirated Miatas, consistently outperforms the Jackson Header and for less money.

Manufactured entirely from 304-stainless steel for superior durability, this 4:1 Miata header is sure to offer many years of enthusiastic Miata performance driving.

Over 200 on-chassis dyno runs allowed Racing Beat to determine the optimum tubing diameter and lengths for both the primary and secondary tubes. Racing Beat also took the opportunity to experiment with various engine-to-header flange porting configurations and collector designs specifically on the Miata application.

This development allowed Racing Beat to fine-tune the performance of this header to achieve performance that is superior to stock at all points of the RPM range. Racing Beat's exclusive cast, stainless steel engine-to-header flange features specially designed exhaust ports that transition smoothly to the primary tubing. Large diameter 1.5" OD tubing has been used for the primary tubing, and then collects into the 2.0" OD secondary.

But, does NOT fit with many Miata supercharger setups. So, get this Miata header if you do not plan to add a supercharger to your Miata.

Note that adding any header makes a slight increase in the exhaust sound level on your Miata. Note that latest version of this Racing Beat Miata Header has a small factory installed dent for clearance to the Miata steering assembly.

NOT CARB LEGAL IN CALIFORNIA (can be used in off road vehicles only). Manual Transmission Only!

. Note that these large exhaust items drop ship direct from Racing Beat and Racing Beat is USUALLY back-ordered on these as they are produced in very small batches. The result is all the headers in that batch are usually spoken for by the time that batch is completed, so they are always stuck in backorder. Don't wait, place your order NOW to "get in line" for a header.


Last week I spoke to Brian, I ordered a aluminum Koyo 37mm radiator for 97 Miata. Brian, you run a first class show! It arrived the next day. It is a fully polished work of art. The welding is perfect. The fit is perfect, old radiator slipped right out, new one slipped right in. Perfect. I am very pleased. Thank you.

Brian, just wanted tyou to know you've got another highly satisfied customer. I got my RoadstersportIII muffler on Friday, installed it in 20 minutes, looks and sounds awesome. I like the baffles out!! My new tires/wheels came Saturday, just got them on and test drove them. Fantastic!! And how they look--- just what I was after. I will add the front "mud flap" that looks like the rear one, for some stone protection, but the offset was just what I was working for. I'd love to send you some pictures for your photo gallery. If you'll send an adress via e-mail, I'll send some high-res photos showing clearances and side profiles, etc. The graphite spokes and polished rims really set well on my black car. Thanks again, me and my wallet will be back!!
