Racing Beat offers a 304-stainless steel cat-back system for the Mazda 3s 5-Door. This cat-back exhaust system is a direct replacement for the factory system and utilizes the stock hangers and mounting brackets for a secure fitment. Manufactured using 2.375" OD stainless steel tubing and cast stainless steel flanges for excellent durability, this straight-through exhaust system is perfect for street or race use. Finished with a 3.5" OD double-walled stainless steel outlet tip, this exhaust system looks as good as it performs.

All Racing Beat exhaust systems are designed by their in-house staff to provide a deep, throaty exhaust tone, without any harsh, buzzy, or raspy tones. Deep and modest under full throttle, and smooth and mellow under highway cruising conditions!

Although they would have preferred to offer a true emissions-legal "bolt-on" system, the design of the stock OEM system makes this very difficult. A quick description of the stock exhaust system on the Mazda 3 is required.

Mazda has designed the stock OEM exhaust system for the Mazda 3 as one long single unit which includes: a catalytic converter, presilencer, main muffler, outlet pipe and tip section. These components are permanently attached to the exhaust tubing and cannot be individually separated. It appears that this exhaust system was installed onto the car and then the rear suspension sub-frame was raised into place. This manufacturing technique makes the removal and installation of any exhaust system on this application a bit more difficult than previous Mazda car models.

In order to retain the emissions legal status of your Mazda 3, the stock catalytic that is included in the OEM exhaust system must be removed from the original exhaust system and retained on the car. Once the stock exhaust has been removed from the car the tubing just behind this catalytic converter can be cut (using a simple hacksaw), and the unit returned to the car. The Racing Beat exhaust system uses slip-joint style fitting and an OEM-style retaining clamp to securely mate our exhaust system to the original catalytic converter outlet tube. The original catalytic converter is retained and the emissions-legal status of your car is still intact!

The 2-piece Racing Beat exhaust system comes complete with all required mounting hardware and fully detailed installation instructions.
