Fitment advice: Designed specifically for manual-transmission Mazda MX-5 ND models, the MZ09 installs between the primary catalytic converter and centre exhaust section. It is compatible with both the standard Mazda cat-back system and compatible Cobra Sport performance exhaust systems.
Other items to consider: Inspect the adjoining exhaust joints, gaskets and mounting hardware during installation. The MZ09 can also be combined with compatible Cobra Sport rear or cat-back exhaust upgrades where a more comprehensive performance exhaust setup is required.
Useful tools / consumables: Vehicle lift or securely rated axle stands, socket and spanner set, penetrating fluid, suitable exhaust-joint tools, torque wrench and exhaust assembly compound where appropriate.
Difficulty guide: Intermediate / professional fitting recommended. Installation requires safe access beneath the vehicle and removal of the original secondary catalyst section between the primary catalyst and centre exhaust.
Why Cobra Sport? Cobra Sport manufactures its performance exhaust systems in the UK using mandrel-bent T304 stainless steel and TIG-welded construction.
