2021+ Mazda 3 Turbo 80mm Cat Back Exhaust System

The 80mm CBE is the ultimate exhaust for those who want the best sound and performance out of your Mazda. The tone is more aggressive than the CS 63.5mm CBE, but refined at the same time giving it the best of both worlds. Check out the sound clips below to listen to what your Mazda will sound like with the CS 80mm Cat Back Exhaust.

The 80mm cat back was optimized for the SkyActiv-G Turbo engine, but will also fit the AWD non-Turbo models if you want a louder more aggressive exhaust tone.


The CorkSport Advantage

Best Mazda 3 Turbo Cat Back  3-inch Exhaust

Optimized Sound:

The CorkSport 80mm Mazda 3 Catback Exhaust was designed specifically for the 2.5L SkyActiv-G Turbo engine as a complete cat-back with unique dual chamber resonators. Because of this, the 80mm exhaust will only be sold as a cat back.

When increasing the piping diameter, commonly more drone is created which is annoying to drive with. We developed the dual chamber resonator specifically for this engine to combat drones in both high and low frequencies.

While retaining the same unique asymmetrical axle back design; we went through multiple resonator setups and this combo proved to offer the best sound with the least drone so you can enjoy the best of both worlds while driving.

Horsepower Gains:

The Mazda 3 Cat-Back Exhaust provides improved horsepower and torque across the entire RPM range vs the OEM exhaust system when tested on a Mazda 3 Turbo model. Gains of 5-13wHP & 5-23wTQ were measured with a DynaPak chassis dyno on an otherwise stock vehicle. After installing, there is no tuning required for your Mazda. Depending on your mods, you may achieve a higher power potential.

OEM Fitment:

Fitment was a major part of the development of the CorkSport 80mm Mazda 3 Cat Back Exhaust. We went to great lengths to ensure that the fitment matched the OEM quality so the installation is spot on. We checked fitment with the stock hatch bumper, appearance kit bumper, and sedan to ensure all setups look and fit as good as the CS 80mm CBE should.

To provide great ground clearance and ample room for the drive shaft, the exhaust was tailored to fit the vehicle.

Materials & Manufacturing:

The CorkSport Mazd 3 80mm Cat Back Exhaust is constructed from 304 stainless steel, mandrel bent, and TIG welded. The Cat Back is then fully polished to provide a great look. We have reinforced the hangers with extra support to make sure they will withstand harsh driving conditions.

2019-2023 Mazda3 Installation Instructions for 80mm Cat Back Exhaust

WOW! Yet another great CS product! These guys nailed it on the sound, performance gain, and ease of installation. It was worth the wait. The sound is deep and tough! No drone inside the cabin but you can definitely hear the growl!
Nice, well mannered exhaust that sounds better the more you drive it.
What's that? I can't hear you over my luxury sport plus mods. the added sound really defines the spirit of this car, no annoying drone and all bark. Inside the cabin is pleasant and the sounds of the intake and exhaust have me driving on the low end of my fuel economy. Fit and Finish are top notch as usual from a CS product
