Show original supplier description

The RoadsterSport Race Muffler is engineered as a performance exhaust upgrade specifically for the 2016-2025 Mazda MX-5 Miata, covering the ND generation. This race muffler is offered alongside a complementary Mid-Pipe, allowing enthusiasts to create a more comprehensive exhaust system. RoadsterSport exhaust systems are generally designed as direct-fit upgrades. They aim to save weight, enhance throttle response, and contribute to a more engaging driving experience. While specific material details like stainless steel construction are common for this brand, this particular listing focuses on the sound profile and application for the ND Miata. Installation of this muffler is typically straightforward, with some sources indicating it can be completed in under a half hour by those familiar with exhaust work, while others suggest a two-hour timeframe and list required tools such as a socket and ratchet set and PB Blaster. The product is eligible for direct shipping, meaning it will be sent from the vendor's warehouse, with estimated delivery within 3-4 business days after the order is processed. An oversize fee of $25.00 applies to this item, and direct ship items are restricted to addresses within the 48 contiguous United States, with no refunds issued for returned direct ship items.
