The Dinan center pipe replaces the resonator in the M235i exhaust. By deleting resonators you can gain a little more volume from the exhaust. This is especially good if you're a fan of the stock exhaust sound and just want to hear more of it. And with less restriction there is a slight horsepower and torque gain as well! This pipe fits best with the Dinan Free Flow rear muffler but will fit on the stock exhaust too.
Note: Only confirmed to fit with the Dinan Free Flow Axle Back and stock exhaust systems. Fitment with other axle back units is not guaranteed.
- Made from 3.25" T304 stainless steel tubing
- Eliminates the resonator creating a deeper, louder, more aggressive sound
