Elevate the sound and performance of your Gen1 MAZDASPEED3 with the COBB Tuning Cat-Back Exhaust, meticulously crafted from 100% 304 stainless steel for long-lasting durability and corrosion resistance. Designed to work seamlessly with the OEM downpipe or any stock-replacement unit like the COBB 3″ Downpipe, this cat-back system ensures a perfect fit with minimal hassle.

The system begins with a stock-style donut flange, allowing for simple bolt-on installation. From there, a polished resonator and low-restriction straight-through muffler deliver an aggressive, deep exhaust tone without compromising drivability. Each section is finished with rolled end caps that give a clean, refined appearance.

At the rear, a slash-cut 3.5″ double-wall tip with an etched COBB logo completes the lookbold, yet tasteful. Best of all, this exhaust system remains within the SAE 95-decibel noise limit, making it 50-state legal and perfect for enthusiasts looking for added performance without attracting unwanted attention.
