Cobra Sport MZ18 Dual Exit Lower Rear Panel Diffuser
Cobra Sport dual-exit lower rear panel diffuser for Mazda MX-5 Mk4 / ND 1.5 and 2.0 models from 2015 onwards fitted with a compatible Cobra Sport dual-exit exhaust system.
The MZ18 has been developed specifically for Cobra Sport's Mazda MX-5 ND dual-exit exhaust conversion. It replaces the visual layout of the standard lower rear bumper area with a purpose-designed panel that accommodates exhaust outlets on both sides of the vehicle, creating Cobra Sport's distinctive quad-tailpipe appearance.
Designed around the MX-5 ND rear bumper, the panel incorporates OEM-style fitting points for accurate positioning and is shaped to align correctly with Cobra Sport's dual-exit exhaust systems. This provides a cleaner and more integrated installation than modifying the standard bumper finish around the additional exhaust outlet.

Fitment advice: The MZ18 should be fitted together with the compatible Cobra Sport dual-exit exhaust system so that the rear panel and tailpipes can be aligned correctly before final installation. Careful trial fitting will help ensure even spacing and positioning of the exhaust outlets on both sides of the vehicle.
Other items to consider: A compatible Cobra Sport dual-exit exhaust system is required to complete the conversion and is sold separately. The MZ18 also requires preparation and painting before final fitment, so professional bodyshop finishing should be allowed for when planning the installation.
Useful tools / consumables: Suitable trim-removal tools, marking and masking equipment, appropriate cutting tools for modification of the original lower rear panel, cleaning and degreasing materials, and the required bodywork preparation and painting materials. Installation adhesive is supplied with the panel.
Difficulty guide: Advanced / professional fitting recommended. Installation requires modification of the original lower rear panel, accurate alignment with the dual-exit exhaust and preparation and painting of the MZ18 before final fitment.
Why Cobra Sport? The MZ18 is designed specifically around Cobra Sport's MX-5 ND dual-exit exhaust layout, providing the correct panel shape and outlet positioning for a properly integrated quad-tailpipe conversion rather than relying on a universal styling solution.
What's in the box: 1x Cobra Sport MZ18 dual-exit lower rear diffuser panel together with the installation adhesive required for fitment. The dual-exit exhaust system is sold separately.
Installation / setup notes: The original lower rear panel must be cut to accommodate installation of the MZ18. The Cobra Sport panel then fits to the OE rear panel using its mounting points and supplied adhesive. The MZ18 is supplied unfinished with a non-UV-protective base coating and must be properly prepared and painted in the chosen finish before installation.
