Designed for those wanting to fit an Aftermarket Manifold, This Special version of SuperQ with added 3.5 inch diameter resonator on the inlet is designed to kill the RASP that is added with adding a standard length highflow manifold to the ND. Otherwise similar to normal SuperQ, see our standard SuperQ product description for more. STRONGLY recommended for those getting a Different Manifold !!

Fits both LHD and RHD, manual and automatic YES, confirmed fit  ND1 ND2 and ND3

Offered in Stainless Steel or Bright Silver Limited edition Ceramic coated  finish. 

Our regular version is polished stainless, which will bronze and blue in response to the heat of use. As a result, got some requests to do bright silver ceramic coating over the polished stainless, which improves long term appearance and performance (about 3% better dyno results with the ceramic coating).

RoadsterSport MAX Torque Stainless Steel Manifold 2.0 Standard length

Fits both RHD and LHD, manual and automatic.

Quality header construction starts with mandrel bent 304 stainless construction, making this the ONLY MX5 manifold choice proudly made in the USA. Beware the choices that are just straight pipe and sharp 90-degree bends welded up in Taiwan and China, they will not last and they will not give max performance in return for the trouble of installing them.

Saves over 3 lbs (1.3kgs) compared to the factory header.

Works with factory manifolds and all aftermarket headers for all MX5's and is a must for supercharger applications. Creative customers have also used these insulated heat shields on everything from Honda Civics to V8 powered race cars.

This attenuation design is a premium "NO-DRONE" choice, great for those who want a throatier sound than stock but still mild. Smooth mandrel bent tubing redirects the flow for a side entrance to the muffler where we engineered a three-chamber design.

It would be much cheaper to just use a single big muffler with nothing but perforated pipe through the centre surrounded by sound absorbing materials but doing it right with the three-chamber design allows us to tailor precisely the FUN sound you want when you push it toward redline, without the harsh drone on decel that the more simple designs make you suffer.

Genuine Mazda ND gaskets Front mid-pipe to Manifold or Rear mid-pipe to silencer. To fit all MK4 MX-5 2016-2023 

Raw catalytic converter with unwelded ends so that you can have your local exhaust shop cut out your old cat and weld this replacement in.

ONLY for those who have our RoadsterSport midpipes for NC (2006-2015) or ND (2016+) MX5.

Glass Packed baffle insert for RoadsterSport TWIN TIPS ONLY. Does not fit RoadsterSport RACE or other mufflers!

Baffle insert for RoadsterSport RACE Single tip and SINGLE TIP Silencers only! Glass Packed baffle insert for RoadsterSport SINGLE TIP Silencers. Intended for single tip SuperQ, the RoadsterSport Race, and the RoadsterSport SuperStreet Single tip.

This 8 inch (20 cm) long baffle packed with sound insulation converts SuperStreet Twin Tip to same sound frequency balance as the single tip RoadsterSport SuperStreet muffler.

This is an evolution of the blocking baffle, adding two more connection positions so you can mix the sound to your preference. We used our new RF to test the 'Mixing Baffle' for the SuperStreet Twin Tip mufflers., allows the owner to mix the ratio of bass to treble and effectively tune the mix to what they want to hear.

For Left Hand Drive only. The billet pedal cover set is inexpensive yet gives an attractive and functional look to your MX5 stock interior.

Replacement factory Mazda "donut" style gasket for the junction between midpipe and muffler on the 2016+ MX5. These live a hard life on the MX5 ND as Mazda made it a flex joint with one flat side and one rounded side and springs in the connection so that as the muffler moves around on the rubber hangers it grinds against the gasket and is held there by just spring tension.

Over time all that grinding slowly wears away the gasket and it gets thinner and less effective.

If you have over 20k miles on your MX5 ND, this is a good addition to your new muffler purchase.

This is a 10" long extension for the primary oxygen sensor for 2016+ MX5.

This extension is not mandatory for our 4-2-1 ND header. The o2 bung on that header is about 1/3rd of the way upstream from the lower flange, and we find that we can usually get the o2 sensor to reach there by just cutting back the wiring loom a bit to get some extra length. However, if you want to avoid that work you can use this extension to make it a simple plug and play install.

For those who really want to hear that great exhaust sound.

This lightweight exhaust silencer with single tip is made with stainless steel 304. Designed it to be the simplest solution to reduce the weight at the back of your car.
