Show original supplier description
Upgrade your Mazda MX-5 NA's exhaust system with the Malian 2.5-inch decat pipe, constructed from durable stainless steel and precision TIG-welded for longevity. The 470mm pipe is designed as a direct-fit replacement for the catalytic converter in specific later-model MX-5 NAs. It is compatible with OEM manifolds and downpipes, simplifying installation. However, it is crucial to verify fitment before purchase, as Mazda utilized different catalytic converter lengths across NA models (89-93: 370mm, 94-97: 440mm, Late 97-98: 475mm). This specific 470mm pipe is intended for the late 97-98 configuration.
