Make your F80 M3 or F82/F83 M4 louder and give the rear of the car a more aggressive look with this quad-tip axle-back exhaust from EOS. It replaces the large factory rear muffler with a dual-muffler setup, 2.5-inch stainless steel piping and four polished 3.5-inch exhaust tips.
This system is made to connect to the factory exhaust. The factory rear pipes must be cut, then the EOS axle-back clamps into place using the supplied hardware.

The factory rear exhaust piping must be measured and cut before the EOS axle-back can be clamped into place. Since the cut location affects exhaust-tip position and alignment, professional installation is recommended.
Watch the Video
Here is a sound clip from EOS showing how this axle-back sounds on the F80 M3 and F82/F83 M4.
Pairs Well With
- Valvetronic Designs 400-Cell Catted Downpipes – Add more S55 turbo and exhaust sound without going catless. These downpipes work upstream of the EOS axle-back and are federal EPA compliant, but they are not CARB legal.
- aFe Momentum Cold Air Intake – Bring out more intake and turbo sound from the S55 while improving airflow. Dry and oiled filter options are available.
- IRL S55 Charge Pipes – Replace the factory charge pipes with aluminum piping, especially if your M3 or M4 is running more boost or already has intake and exhaust upgrades.
