Borla Mazda3 Catback Exhaust

When you open the box for this Borla cat-back exhaust system, you'll find the main exhaust piping, the muffler assembly, and a 4-inch round polished T-304 stainless steel tip. This system is specifically designed for the 2004-2009 Mazda 3 with the 2.3L engine, and it works with both automatic and manual transmissions, whether you have the sedan or hatchback body style.

Borla has been around for a long time, and they really know how to tune an exhaust. This S-Type system is built from aerospace-grade T-304 stainless steel, which is a strong material that resists corrosion really well. They've engineered it to give you a noticeable improvement in airflow – about 14% better than stock – and that translates into solid performance gains across the entire RPM range. You'll get that classic Borla sound, often described as a 'sonic shot of adrenaline,' but without any annoying drone inside the cabin. It's lighter than the factory exhaust, too, which always helps.

Installing this system is a straightforward bolt-on job, meaning you won't need to do any welding. It's designed to fit right onto your Mazda 3, making the upgrade process much simpler. Borla backs this system with a Million-Mile Warranty, which shows how confident they are in its durability and build quality.
