Around 3 years ago the 80mm Cat Back Exhaust was released for the 3rd Gen Mazda 3. During this time many have enjoyed the increased sound, performance and looks that it offers. As we have been developing the Turbo Kit for the 2.5L 3rd Gen Mazda 3, we have also had a chance to refine and tune the 80mm Cat Back Exhaust to further improve the tone and sound of the exhaust while reducing drone for 3’s equipped with the Turbo Kit. That is why we are excited to release the Turbo Kit specific 80mm Cat Back Exhaust to those of you who have or are looking to pick up the Turbo Kit for your 2014-2018 2.5L Mazda 3.
With the original 80mm CBE installed on our Turbo Kit equipped Mazda 3, we found that while the sound was good, the drone it created in the cabin was too aggressive for our liking. To combat this we tested multiple different combinations of midpipes and axle backs with different resonator configurations to find the best solution. From this testing we found that the combo that worked best was to keep the same midpipe setup, but to modify the axle back so that no resonators were used. This resulted in a substantial reduction in drone while adding in a more aggressive tone at higher RPM’s. With that being said if you are upgrading from a stock or 60.5mm exhaust it will be a large increase in NVH (Noise, Vibration, and Harshness) but this is offset in our opinion by the tons of fun noises it offers. Since the axle back is the only component that has been changed for the Turbo Kit specific exhaust, if you already have an 80mm CBE and want to upgrade, all you have to get is the non-resonated axle back to take advantage of the reduced drone and improved sound. To get a good idea of how the 80mm CBE will sound during different driving conditions, check out the video below.
The Turbo Kit 80mm CBE also provides the same great appearance of the original 80mm CBE. Both the sedan and hatchback exhausts feature 100mm or ~4” tips. On the hatchback this helps fill out the bumper cutouts and the slant cut design helps them match the flow of the bumper profile. The sedan on the other hand, features a single wall design so that water and other debris don’t get caught in the tip since they are hidden behind the bumper and angled down. No matter which model you have, these features help the rear of the car stand out and provide an aftermarket look that is subtle and classy as it should have been from the factory.
The great build quality and material are also carried over from the original 80mm Cat Back Exhaust with the use of T-304 stainless steel that is polished to a mirror like finish. This helps keep the CBE looking new and protects against corrosion for a long time to come. All joints are TIG welded to ensure durability along with a nice appearance. The resonators use a flow-thru design so exhaust flow remains uninterrupted while drone is kept down. Check out the product page for more pictures and details on the Turbo Kit 80mm CBE.
