Description

The Cobalt 909-680 is a premium dual-exit stainless steel muffler specifically engineered for the Mazda MX-5 Miata NB models from 1999 to 2015. Every weld on the Cobalt 909-680 is meticulously ground smooth and polished, ensuring a clean, high-end finish. The entire muffler assembly is then polished to a brilliant mirror shine, reflecting the quality craftsmanship and attention to detail. This dual-exit design not only enhances the visual appeal of the rear of the vehicle but also contributes to a sportier exhaust note. While specific sound profiles can vary, user feedback suggests it offers a noticeable enhancement over stock, particularly at higher RPMs, without excessive highway drone. Its stainless steel construction ensures durability and resistance to corrosion, making it a long-lasting upgrade for your Miata.
