Experience the ideal balance of volume and refinement with the IRL G05 X5 40i Catback Exhaust System. Designed to improve exhaust flow and overall performance, this system delivers a deeper, sportier tone while maintaining the ability to switch back to a more OEM style sound at the push of a button.

The included IRL valve controller allows you to fully utilize the electronic exhaust valves and adjust sound levels as desired.

Features

• Larger diameter piping for increased exhaust flow
• Noticeable horsepower and torque improvements
• IRL valve controller included
• Full 304 stainless steel construction
