EOS Exhaust for Mazda3 BP Hatchback (19-26) CX-30 (20-26) Muffler Delete w/ Burnt Tips

Make your Mazda3 Hatchback or CX-30 louder and give the rear of the car a more aggressive look with this muffler-delete axle-back from EOS. It replaces the large factory rear muffler with a free-flowing dual-exit section, so you get more exhaust sound without replacing the entire system.

The axle-back is made from T-304 stainless steel with 2.5-inch piping and dual 4-inch burnt tips. Since this is a muffler delete, expect it to be noticeably louder than the factory exhaust with more sound during cold starts and acceleration. You may also hear additional drone at certain cruising speeds.
