Cobra Sport high-flow sports catalyst front and centre performance exhaust for Mazda MX-5 Mk3 / NC 1.8 and 2.0 models from 2005–2014 applications listed in the compatibility table.
The MZ20 replaces the original front and centre exhaust sections from the manifold rearwards, combining freer-flowing 2.5" / 63.5 mm pipework with a high-flow sports catalyst. It is designed for customers looking to upgrade the restrictive front section while retaining a catalytic converter within the exhaust system.
Manufactured in the UK from certified grade 304 stainless steel using TIG-welded construction, the MZ20 forms the front and centre performance section of Cobra Sport's MX-5 NC exhaust range and can be combined with a compatible Cobra Sport rear exhaust for a more comprehensive system upgrade.

Emissions / catalyst notes: The MZ20 replaces the original catalytic converter with a high-flow sports catalyst. Cobra Sport states that this sports-cat version is not EC homologated and may not meet road-use or emissions requirements in every territory. Vehicle owners are responsible for ensuring that the completed vehicle complies with all applicable road-use, emissions and inspection requirements.
Tuning notes: Cobra Sport advises that an engine-management light may illuminate after replacing the standard catalyst. ECU recalibration may be required to address this and correctly accommodate the revised exhaust configuration.
Fitment advice: The MZ20 fits from the exhaust manifold rearwards and replaces both the front and centre exhaust sections. During installation, loosely assemble and align the replacement sections before fully tightening all joints to ensure correct positioning and clearance throughout the system.
Other items to consider: Inspect the rear exhaust section, mounting rubbers and adjoining connections while the original front and centre sections are removed. The MZ20 can be paired with a compatible Cobra Sport rear exhaust to complete a wider performance exhaust upgrade.
Useful tools / consumables: Vehicle lift or securely rated axle stands, socket and spanner set, penetrating fluid, exhaust-hanger removal tool or suitable pliers, torque wrench and suitable exhaust assembly compound where required.
Difficulty guide: Advanced / professional fitting recommended. Installation involves removal of the original front and centre exhaust sections, work close to the exhaust manifold and catalyst area, and accurate alignment of several exhaust joints.
