Unlock performance while keeping your exhaust system street-friendly with the Magnaflow High-Flow Replacement Converter. Designed to fit seamlessly with our popular 2.5" midpipes for NA, NB, and NC Miata applications, this converter is built to handle serious flow without restriction.

Available in both 4" and 5" body diameters, the unit provides a significantly larger surface area compared to stock converters. The 4" version offers excellent balance between compact fitment and high performance, while the 5" version takes it even further, maximizing exhaust volume capacity for reduced backpressure and increased efficiency.

Constructed with proven high-quality materials and precision manufacturing, this converter ensures durability and long-lasting performance under demanding conditions. Whether your Miata is a daily driver, weekend cruiser, or track-ready build, this upgrade delivers the flow you need to support your power goals without choking your exhaust system.
