Borla 99-05 Mazda Miata Rear Muffler

This Borla S-Type axle-back exhaust system is built from premium T-304 stainless steel, which is stronger and more corrosion-resistant than T-400 series stainless steel. It's designed to connect to your factory mid-pipe, making it an axle-back system that replaces the rear section of your exhaust. This means you get a noticeable change in sound and potentially improved exhaust flow without needing to replace the entire exhaust system.

The S-Type designation means Borla tuned this muffler for a more aggressive sound than their touring models, but it's still designed to be manageable for daily driving. You'll notice an improved exhaust note that lets you hear the engine working, especially under acceleration. The ultra-smooth mandrel bends used in its construction help maintain exhaust gas velocity, which can contribute to a slight increase in horsepower and throttle response. This system is precision manufactured for an accurate fit, and installation is typically a straightforward bolt-on process.

Borla backs this exhaust system with a Million-Mile Warranty, reflecting their confidence in the durability and quality of their T-304 stainless steel construction. This system is specifically for the 1999-2005 Mazda Miata MX-5 NB with the 1.8L 4-cylinder engine and manual transmission.
