Cobra Sport MZ14 Non-Resonated Centre Exit Cat-Back Performance Exhaust
Cobra Sport non-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 MZ14 is Cobra Sport's non-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 substantially different rear-end appearance.
The system uses 2.5" / 63.5 mm mandrel-bent T304 stainless-steel pipework with TIG-welded construction. As the non-resonated version, the MZ14 omits the centre silencer used by the resonated alternative, giving a louder and more pronounced exhaust character.

Exhaust configuration: This is the non-resonated MZ14 centre-exit system. It omits the centre silencer fitted to the resonated centre-exit version and is therefore the louder configuration.
Sound: The non-resonated configuration provides the louder and more pronounced option within Cobra Sport's centre-exit ND cat-back range.
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 side-exit arrangement to a centre-exit configuration and is designed to work with the dedicated Cobra Sport centre-exit lower rear panel.
Other items to consider: The Cobra Sport centre-exit lower rear panel / diffuser is required for the intended installation and is sold separately. It is not included with this exhaust system. Inspect the existing exhaust mounting rubbers and adjoining flange areas 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, trim / cutting tools suitable for modifying the rear panel area, torque wrench and suitable exhaust assembly compound where appropriate.
Difficulty guide: Advanced / professional fitting recommended. The exhaust itself is a multi-section cat-back installation, and the centre-exit conversion additionally requires fitting the dedicated lower rear panel and modification of the original rear-panel area.
Why Cobra Sport? Cobra Sport manufactures its performance exhaust systems in the UK using certified grade 304 stainless steel and TIG-welded construction. The MZ14 combines 2.5" mandrel-bent pipework with a distinctive centre-exit layout and non-resonated configuration for customers wanting both a stronger visual change and a more pronounced exhaust character.
What's in the box: Cobra Sport MZ14 non-resonated centre-exit cat-back exhaust comprising the replacement centre and rear exhaust sections with the selected YTP03 or YTP16 tailpipe option. Relevant exhaust fittings and gaskets are supplied. The centre-exit lower rear panel / diffuser is not included.
Installation / setup notes: The exhaust fits from the second catalytic-converter section rearwards. A Cobra Sport centre-exit lower rear panel is required for the intended installation. Cobra Sport states that installation of this panel requires an incision to be made in the original rear panel area; the replacement panel is supplied unfinished and requires painting before fitment. Assemble the exhaust with joints initially loose, align the centre outlets accurately with the replacement panel aperture and only then fully tighten the system.
Warranty: Cobra Sport currently offers a lifetime guarantee to the original purchaser on eligible car exhaust systems, subject to its published terms and exclusions. Registration requirements and the current Cobra Sport warranty terms should be followed to retain the applicable extended coverage.
