Description
Looking to transform your BMW X3 M40i or X4 M40i into a true performance masterpiece? The Dinan Valved Cat-Back Exhaust System delivers an unparalleled auditory and visual upgrade, combining cutting-edge engineering with impeccable craftsmanship. This exhaust system enhances the sound, appearance, and performance of your G01 or G02 platform, making every drive an unforgettable experience.
Designed to be a direct bolt-on upgrade, the system requires no cutting or welding and uses factory mounting locations for a seamless installation. Crafted from 100% T304 stainless steel with precision TIG welding, this exhaust system offers enhanced durability and a refined look that outshines its predecessor. The highlight of this upgrade is the bold M-inspired quad tip design, replacing the stock dual slip tips with individually functioning 3.75-inch tips available in black ceramic or polished stainless steel.
The Dinan exhaust doesn’t just look exceptional—it sounds extraordinary. By eliminating the restrictive central resonator and incorporating a Helmholtz-equipped muffler, the system achieves a deeper, throatier tone while minimizing drone inside the cabin. Retaining the factory valve functionality, this setup offers versatile sound dynamics, delivering a subdued rumble at low RPMs and a roaring performance-inspired note at high RPMs. For those who desire even greater control, the system can be paired with an exhaust valve remote, giving you the power to adjust the sound on demand.
With larger diameter piping (83mm vs. 80mm stock), optimized flow, and a lighter weight than the factory system, the Dinan Valved Cat-Back Exhaust enhances performance by delivering gains of up to +6 HP and +5 lb-ft of torque. This system embodies Dinan's commitment to performance and luxury, ensuring you never compromise on style, sound, or driving enjoyment.
