Enhance Your BMW X3 M40i / X4 M40i with the Dinan D660-0099 Cat-Back Exhaust System
If you're a proud owner of a 2018-2025 BMW X3 M40i or X4 M40i and you're looking to elevate your driving experience, the D660-0099 Cat-Back Exhaust System from Dinan is the upgrade you need. This exhaust system not only amplifies the sound of your ride but also enhances its visual appeal with a stunning quad tip design. Say goodbye to the mundane and hello to a more exhilarating auditory experience!
Installation Made Easy
The D660-0099 is designed for a straightforward, bolt-on installation that requires no cutting or welding. Utilizing factory mounting locations, you can install this system with minimal hassle, making it a perfect choice for DIY enthusiasts. Crafted from 100% brushed T304 stainless steel and TIG welded, this exhaust system is built to last while providing a significant upgrade over the stock setup.
Stunning Quad Tip Design
One of the standout features of the D660-0099 is its M-inspired quad tip configuration. Each tip measures 3.75 inches (95mm) and is available in either polished stainless steel or a sleek black ceramic finish. This design not only looks aggressive but also ensures that your exhaust system is as functional as it is attractive, offering four distinct pathways for exhaust flow.
Performance You Can Hear and Feel
Performance is where the Dinan exhaust truly shines. By eliminating the central collector and resonator, this system promotes a freer flow of exhaust gases, resulting in a maximum gain of +6 horsepower and +5 lb-ft of torque at 6600 RPM. The larger diameter piping (83mm vs. 80mm) enhances flow, while the Helmholtz-equipped muffler combats drone, allowing for a refined sound during cruising and a thrilling roar when you hit the throttle.
Versatility in Sound
The D660-0099 retains the factory valve functionality, allowing you to switch between a refined sound at low RPMs and a more aggressive tone at higher RPMs. For those who want even more control, consider pairing it with an exhaust valve remote to adjust the sound on the fly. Open the valves for a straight-pipe experience or close them for a more subdued output—perfect for any driving situation!
Key Features:
- Maximum gains of +6 HP and +5 lb-ft of torque
- Enjoyably louder, sportier sound with a delightful octave drop
- Drone abatement technologies to reduce cabin resonance
- Quad 3.75-inch double-walled tips with laser-engraved Dinan logo
