Description
The layout of this COBB 3" SS Cat-back was chosen to minimize the total bend degrees used to route the exhaust piping for reduced back pressure. The entire system fits within the factory exhaust path to allow the exhaust to be tucked up as close to the undercarriage as possible to achieve maximum ground clearance. Exhaust piping is 3" diameter from the downpipe to the split, where dual 2.5" pipes whisk the exhaust out of the system. The resulting path of least resistance minimizes back-pressure for maximum power gains. Harsh engine exhaust noise is subdued via one primary resonator and one secondary resonator. These chambered resonators provide sound reduction without adding restriction to the exhaust flow. The resulting mellow rumble sounds and feels powerful, without being overbearing. This exhaust was designed to meet the 95dB sound restriction even when used as part of a full turbo-back exhaust system. Significant effort went into making this exhaust look as good as it sounds and performs. Both resonators are custom built and finished with beautiful welds. The 2.5" and 3" stainless steel piping has a satin finish for a stunning appearance. The exhaust is finished with two 4" slash-cut, double-wall rolled tips with laser etched COBB logos. The entire kit is constructed of T304 stainless steel to ensure that it stays looking this great for years to come. This cat-back exhaust will work with the stock or any direct factory replacement downpipe. The two bolt flanges allow slight adjustability for absolutely perfect fitment. Includes all gaskets and hardware, and uses the stock doughnut gasket to mate to the downpipe.
Why?
The COBB Tuning 3" SS Catback Exhaust was engineered specifically to match the performance needs of the 2010-2013 MAZDASPEED3. The design of this Gen2 MAZDASPEED3 cat-back exhaust focused on three specific areas; reduced back-pressure for increased power potential, compliance with sound regulations when used in a full turbo-back exhaust system, and eye-popping styling. The final product is an over-achiever!

COBB Mazdaspeed3 Gen2 3″ Cat-Back Exhaust – FAQ
Does this exhaust fit my Mazdaspeed3?
Yes. This COBB 3″ cat-back exhaust is designed specifically for the second-generation Mazdaspeed3 (2010–2013). It is not compatible with first-generation Mazdaspeed3 models.
Is this a full exhaust system or just a cat-back?
This is a cat-back exhaust system. It replaces the exhaust components from the catalytic converter back, including the mid-pipe, resonators, and mufflers.
What size is the piping?
The system features a 3″ primary exhaust pipe that transitions into dual 2.5″ rear sections. This design improves exhaust flow while maintaining balanced performance and sound.
What material is the exhaust made from?
The COBB cat-back exhaust is constructed entirely from T304 stainless steel, providing excellent durability, corrosion resistance, and long-term performance.
How does this exhaust sound?
The COBB cat-back exhaust delivers a deep, sporty tone that is more aggressive than stock without being overly loud. Integrated resonators help reduce harshness and unwanted drone, making it suitable for daily driving.
Sound characteristics:
Will this exhaust increase horsepower?
Yes. By reducing exhaust restriction and backpressure, the COBB 3″ cat-back exhaust can support improved exhaust flow and performance, especially when paired with other modifications such as an upgraded downpipe or tune. Actual gains vary depending on the vehicle setup.
Is this exhaust compatible with aftermarket downpipes?
Yes. The COBB cat-back exhaust is designed to work with stock, COBB, and most direct-replacement aftermarket downpipes.
Does this exhaust require tuning?
No tuning is required to install this cat-back exhaust. However, tuning can help maximize performance when combined with additional modifications.
Is installation difficult?
Installation is straightforward and bolt-on. The system uses factory mounting points and included hardware. Professional installation is recommended but not required.
Typical installation time:
Does this exhaust come with exhaust tips?
Yes. The system includes dual 4″ double-wall slash-cut exhaust tips with a premium finish and COBB branding.
Will this exhaust trigger a check engine light?
No. Because this is a cat-back exhaust and does not alter catalytic converters or sensors, it will not trigger a check engine light.
Is this exhaust street legal?
Since this is a cat-back exhaust, it is generally legal for street use. However, sound regulations vary by state and local laws. Always check local regulations.
Why choose the COBB cat-back exhaust over others?
The COBB system is engineered specifically for the Mazdaspeed3 platform and offers a balance of performance, sound quality, and build quality. Compared to many aftermarket systems, it prioritizes refined sound, premium materials, and precise fitment.
