Keep Your COBB Exhaust Firmly in Place on the 2007-2009 Mazdaspeed3
The COBB 571001 Mazdaspeed3 Gen1 Exhaust Hanger Kit replaces the factory rubber hangers on 2007-2009 Mazdaspeed3 hatchbacks with a complete set of high-durability urethane mounts. The stock rubber hangers are soft by design, which allows your exhaust to sway, tap the subframe, or contact the exhaust tunnel under hard cornering and aggressive driving. Upgrading to urethane eliminates that movement and reduces the occasional rattle or rubbing that plagues stock and aftermarket exhaust systems on spirited Mazdaspeed3 builds.
Key Features
- COBB 571001 complete hanger kit includes all 4 hangers required for a full Mazdaspeed3 Gen1 exhaust system
- High-durability urethane construction significantly more rigid than factory rubber mounts
- Reduces excessive exhaust movement that causes rattles, subframe contact, and exhaust tunnel rubbing
- Includes 3 twist-in style hangers and 1 two-hole conventional hanger for full system coverage
- Exact replacement dimensions for direct fitment on 2007-2009 Mazdaspeed3
- Designed to work with both the COBB 571100 SS 3-inch Cat-Back Exhaust and aftermarket exhaust systems
- No modifications required for installation on Gen1 Mazdaspeed3 hatchbacks

Frequently Asked Questions
What years does the COBB 571001 exhaust hanger kit fit?The COBB 571001 is designed specifically for the first generation Mazdaspeed3, covering model years 2007, 2008, and 2009. It does not fit the second generation Mazdaspeed3 produced from 2010 to 2013. If you have a Gen2 Mazdaspeed3, look for the COBB Gen2 specific hanger kit.
Why should I replace my factory exhaust hangers with urethane?The factory rubber hangers are intentionally soft to isolate NVH (noise, vibration, and harshness) in a comfort-oriented stock vehicle. However, with a performance exhaust installed, that softness allows the system to sway and occasionally contact the subframe or exhaust tunnel under hard driving. Urethane is significantly more rigid, reducing movement and eliminating the rattles and contact that aftermarket exhaust owners commonly experience.
Does the COBB 571001 kit include everything I need to replace all the hangers on my Mazdaspeed3?Yes. The kit includes all 4 hangers needed for the complete Mazdaspeed3 Gen1 exhaust system. There are 3 twist-in hangers and 1 two-hole conventional hanger. No additional pieces are required for a full replacement.
Will the COBB 571001 hangers work with my non-COBB aftermarket exhaust?Yes. The COBB 571001 hangers are replacement pieces for the factory hanger mounting points on the 2007-2009 Mazdaspeed3. As long as your aftermarket exhaust uses the same hanger loop points as the factory system, these urethane mounts will work with it. They are not exclusive to the COBB cat-back exhaust.
How difficult is it to install the COBB 571001 exhaust hangers?Installation is straightforward with basic hand tools. You will need exhaust hanger removal pliers (or a flathead screwdriver with some effort) and silicone spray lubricant to ease the urethane hangers into place. The twist-in hangers require rotating them into the mounting hooks, while the two-hole conventional hanger slides straight onto the posts. Total install time is typically under 30 minutes with the car safely raised on jack stands.
Will urethane exhaust hangers increase cabin noise or vibration on my Mazdaspeed3?Urethane does transmit slightly more vibration than rubber due to its greater rigidity, which is the same property that reduces exhaust movement. Most Mazdaspeed3 owners report the increase in cabin noise or vibration is minimal and well within acceptable range, particularly when paired with an aftermarket exhaust that already changes the sound signature. The tradeoff in reduced rattling and exhaust movement is generally considered worthwhile.
Are these hangers a direct bolt-on replacement for the Gen1 Mazdaspeed3 or do they require modification?These are direct replacement hangers requiring no modification to the vehicle or exhaust. They install in the same positions as the factory rubber mounts using the existing hanger hooks and mounting posts on the 2007-2009 Mazdaspeed3.
Can the COBB 571001 hangers be used on the standard Mazda 3 (non-Mazdaspeed) from 2007-2009?The COBB 571001 is specifically designed and tested for the 2007-2009 Mazdaspeed3 exhaust system layout. The standard Mazda 3 may have different hanger configurations depending on trim and engine. COBB does not list the standard Mazda 3 as a compatible application for this kit, so it is recommended to verify your vehicle's hanger points before purchasing.
Installation Instructions
- Safely raise and support the vehicle on jack stands, ensuring adequate clearance to work under the exhaust system.
- Apply silicone spray lubricant generously to the factory rubber hangers and the mounting hooks to ease removal.
- Use exhaust hanger removal pliers or a flathead screwdriver to pry each factory rubber hanger off its mounting hook, starting from the rear and working forward.
- Apply silicone spray lubricant to the new COBB urethane hangers before installation to ease fitment.
- Install the 3 twist-in urethane hangers by aligning the loop with the mounting hook and rotating the hanger to lock it into position.
- Install the 1 two-hole conventional urethane hanger by sliding it straight onto the mounting posts at its designated location.
- Verify that the exhaust system is properly seated and all 4 hangers are fully engaged before lowering the vehicle.
- Start the engine and check for any unusual vibration or contact with the subframe or tunnel, making minor position adjustments if needed.
