Na Miata Carb Legal Header

A great catted header option for anyone with a right-hand drive car who wants to keep emissions at bay. I paired this with Helmholtz Midpipe and my MX5 now has the exhaust quality you`d expect from a sporty roadster, just the right amount of Burble & Volume. It only took a few trips to settle into the system and deepen the tone of the exhaust. From a performance perspective, the engine feels much more responsive and free due to improved exhaust gas flow. I highly recommend this combination, exactly what I was looking for. Installation Notes: Brian`s instructions in the GWR forum for installing the header are on money and extremely useful. Make sure you have a complete toolbox and good access under the car before attempting this installation. You`ll need an O2 jack, circuit breaker rods, 1/4″ and 3/8″ power sets, threaded anti-seizing spray, and plenty of patience to remove factory connections. The new header installation is quite simple and is what you expect. Even if your car is right-hand driven, you`ll need to remove the steering column clutch to pull out the factory strips and get new headers.

Make sure you align the clutch correctly when you reinstall it, otherwise you`ll end up with a warning light on the dashboard and an off-center steering wheel. Developed after hours of bench testing and overhauls, every aspect of the Racing Beat header has been analyzed and tuned to maximize optional power and torque for all model year applications. From our custom stainless steel casting flange, primary and secondary pipe diameters and lengths, manifold design and internal configuration, molded outlet flange and seal design, every aspect of our manifolds has been bench tested and retested to achieve maximum average and maximum performance. There simply isn`t a better header on the market! DO NOT wrap headers. Header packaging voids the warranty for any header brand. The casing traps moisture and also collects oil emissions under the hood like any oil leak (meaning you can possibly have a fire). The result is a rapid deterioration of the beautiful polished stainless steel surface and welds. Header packaging is something that comes from drag racing, but professional drag racers know that it kills the header in exchange for another 1- or 2-horsepower rinse benefit, and they accept that it also means they can rebuild the headers at the end of each racing season. Instead of wrapping letterheads, consider our ceramic-coated versions or top heating blankets (which don`t retain moisture).

Suitable for all legal NC Generation Miatas and CARB for 2006-2015. If you want the best midpipe performance, choose Cobalt. Designed by our in-house engineering and R&D team with guidance from our Californian neighbor Magnaflow. 2.5″ all-steel pipes and welded catalytic converter, these screws to collectors and factory silencers or cobalt. Location of the factory O2 connection. Ideal for Miatas with compressor, turbo or naturally aspirated engine. When Moss, Cobalt and Magnaflow work together, you get the best product. CARB legal. You know that when you get home after being in public, take off your mask and think “now I can breathe.” Well, that was my roadster experience after installing the Magnaflow manifold combination and intermediate hose. I highly recommend this product, you will not be disappointed! Want a review of my recently purchased GWR Carb header and Mid Pipe? I know you can`t say that one of the two products increases performance, but I can.

In combination with the Super Q, the Exhause sound is also amazing. Before, I felt that the Super Q was too quiet and I wanted to order the street single. This configuration rumbles at low revs, buzzes under compression and growls like a beast when you get to the red line. Dan Racing Beat developed the state-of-the-art technology of Miata manifold technology, using both the chassis dynamometer and road testing. Their headers include a 4-in-1 configuration tuned to optimize exhaust gas purification and power output while improving exhaust sound. Hundreds of hours of development and more than 200 hours on the test bench were spent refining this header. The Racing Beat 4:1 header has been tuned to allow for power and torque improvements across the rev range. The equal-length manifold uses 14-gauge polished stainless steel tubes and thick cast stainless steel flanges.

Not suitable for Jackson Racing compressor. Only for manual transmissions. Not CARB approved and cannot ship to an address in the State of California. Magnaflow has pretty cleaned up the design with this CARB version, production image below of the legal CARB replacement, full diameter primary colors that are NOT clamped in half: Miata headers are a great way to add performance and responsiveness to any Miata. Every Miata manifold sold here contains the downstream seal needed for installation (and the motor connection seal is made of reusable stainless steel that does NOT need to be replaced to install a new Miata manifold). Here`s my review of the Carb Legal Header 61-2340B and Mid Pipe 61-2199. Feel free to use anything, all or nothing. Sorry it`s so long, but I had a lot of good things to say! I was totally prepared to be overwhelmed by this mod when reading the descriptions on Goodwin`s website.

My OEM header catalyst had failed and I needed a replacement. OEM is such a terrible design, I didn`t want to become an OEM even if it was cheaper. Since I was living in California, I needed a legal assignment from CARB. Since I made the header, I decided to upgrade the midpipe as well. Both units are manufactured by Magnaflow and distributed by GWR. I was pleasantly surprised by the improved torque at low revs and the increased power up to the red line. My NC now comes out of corners much better when revs are low. Previously, there was no power up to 4000 rpm. The car also drives much faster up to the rev limiter. It doesn`t seem to weigh more than 5000 rpm.

On a track I still ride, I was driving 10 miles per hour faster than my normal pace, with far fewer downshifts to stay within the performance band. I have a GWR Super Q silencer. My only complaint about it was that it always seemed a little too quiet. I heard more intake noise than exhaust noise during strong acceleration. This has changed significantly with the new header and intermediate channel. The empty tone is now deep and rumbling. Under deceleration, there is now a beautiful deep splash. Zero drones at any speed. At high acceleration, the car sounds like a real sports car and screams at the red line at 7800. Not boringly noisy, but just enough for a sports car. I have always said that the most important upgrade to my CL3 power supply is an ECU setting. I think the combination of the header and the middle of the pipe could match this increase.

Not designed as a performance upgrade, essentially a bearing replacement and that means primary bearing size colors (albeit without the compression curves of the terrible OEM design). So don`t expect big gains, but expect both to circulate much better than inventory and the O2 sensor lights to stay off and smog to occur if properly installed on NC generation Waitas. — MICHAEL S., San Francisco Bay Area ( MX5 2006 Grand Touring Roadster ) August 2020 — Shawn M., Brisbane, Australia ( Mazda MX5 NC ) December 2020 The MagnaFlow exhaust manifold with integrated catalytic converter is designed for easy-to-screw installation and requires no cutting or welding. Have American made stainless steel construction and high quality and efficient honeycomb monolithic catalyst designed for long service life and clean emissions.
