CorkSport | Cat-Back Exhaust System 80mm - Mazda 3 Hatch with Appearance Kit Turbo 2021+

CorkSport - 2021+ Mazda 3 Turbo 80mm Cat Back Exhaust System

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.

Complete Install

Included with each exhaust is all of the necessary hardware and gaskets so the installation can be completed quickly without any interruptions.
