Cobra Sport MZ12 Resonated Centre Exit Cat-Back Performance Exhaust
Cobra Sport resonated centre-exit cat-back performance exhaust for Mazda MX-5 Mk4 / ND 1.5 and 2.0 models from 2015 onwards applications listed in the compatibility table.
The MZ12 is Cobra Sport's resonated centre-exit cat-back conversion for the fourth-generation Mazda MX-5. It fits from the second catalytic-converter section rearwards and replaces the original centre and rear exhaust sections, relocating the exhaust outlets to the centre of the rear bumper area for a distinctive centre-exit appearance.
The system uses 2.5" / 63.5 mm pipework and incorporates a centre silencer. This makes the MZ12 the resonated version of Cobra Sport's centre-exit ND system, providing a subtler but still sporty exhaust tone compared with the louder non-resonated MZ14 configuration.

Exhaust configuration: This is the resonated MZ12 centre-exit system and includes a centre silencer. Cobra Sport also offers the corresponding MZ14 non-resonated configuration, which omits this silencer and provides the louder exhaust option.
Sound: Cobra Sport describes the resonated configuration as providing a subtle but sporty tone. It is the more controlled-sounding centre-exit configuration compared with the non-resonated alternative.
Fitment advice: Designed for Mazda MX-5 Mk4 / ND 1.5 and 2.0 models from 2015 onwards. This system converts the car from its original exhaust outlet arrangement to a centre-exit configuration and requires the dedicated Cobra Sport centre-exit lower rear panel / diffuser for the intended installation.
Other items to consider: The dedicated Cobra Sport centre-exit lower rear panel / diffuser is required and is sold separately; it is not included with this exhaust system. It is also sensible to inspect the existing exhaust mounting rubbers and adjoining flange area during installation and replace worn components where necessary.
Useful tools / consumables: Vehicle lift or securely rated axle stands, socket and spanner set, penetrating fluid, exhaust-hanger removal tool or suitable pliers, appropriate trim / panel tools for installation of the centre-exit rear panel, torque wrench and suitable exhaust assembly compound where required.
Difficulty guide: Advanced / professional fitting recommended. Installation involves removal of the original centre and rear exhaust sections, fitting and aligning a multi-section cat-back system and installation of the required centre-exit lower rear panel.
Why Cobra Sport? Cobra Sport manufactures its performance exhaust systems in Sheffield, UK using certified grade 304 stainless steel, mandrel-bent pipework and TIG-welded construction. The MZ12 combines a distinctive centre-exit appearance with a resonated centre section for customers wanting a sportier exhaust note without choosing the louder non-resonated configuration.
What's in the box: Cobra Sport MZ12 resonated centre-exit cat-back exhaust comprising the replacement centre and rear exhaust sections with the selected YTP03 or YTP16 tailpipe option. Cobra Sport confirms that all relevant exhaust fittings and gaskets are supplied. The required centre-exit lower rear panel / diffuser is not included.
Installation / setup notes: The exhaust fits from the second catalytic-converter section rearwards. The dedicated centre-exit lower rear panel / diffuser must be fitted separately. During installation, loosely assemble the exhaust sections first, position the system without placing unnecessary load on the exhaust hangers, align the centre outlets accurately with the rear-panel aperture and only then fully tighten the exhaust joints.
Warranty: Cobra Sport currently offers its lifetime guarantee to the original purchaser on eligible car exhaust systems when the exhaust is registered online with Cobra Sport within 28 days of receipt, subject to its published terms and exclusions. Products not registered within 28 days are subject to Cobra Sport's standard one-year manufacturing warranty.
