To achieve desired sound volume and tone Dinan felt becoming of the F9x X5M/X6M the tubing was enlarged to 83mm (vs 80mm stock) to allow freer flow throughout the entirety of the system. The larger tubing is fed into a muffler that is typical of all Dinan exhaust design and utilizes absorption and reactive technologies designed to improve exhaust flow and reduce backpressure. The combination results in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. This is partly courtesy of the retained computer-controlled exhaust valves that limit noise during low-speed driving and open fully during high-load conditions to allow free flow and greater sound as the bulk of the gases are bypassing the muffler. Like all Dinan exhausts, our X5M/X6M free flow exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. With the Dinan exhaust equipped on the X5M/X6M you get the best of both worlds; aggressive tone/sound and civility. A combination that is quintessential of the luxury SUV with a penchant for aggressive behavior.
Sound isn't the only aspect of the exhaust that has been modified. The Dinan F9x X5M/X6M exhaust has been skillfully crafted entirely out of T304 stainless steel and TIG welded for the best visual appearance and color. The entire system is then brush finished to further guarantee an immaculate looking system out of the box. The attention to detail is not limited to parts of the system you can't see once the exhaust is installed but is also extended to the exhaust tips themselves. The Dinan exhaust sports massive, quad 4.5" (114mm) clamp-on, double-walled, polished stainless steel and laser engraved exhaust tips that are befitting of the big Bavarian beast. The tips masterfully fill up and accentuate upon the factory cut-outs showcasing an extremely aggressive, yet refined, styling that will force people to take notice even before it is heard.
The argument as to what performance SUV is placed atop the performance pyramid always seems to come to an end when the BMW X5M (or X6M) enters the conversation. The burly vehicles are intimidating due to their size yet still remarkably agile and quick given their heft making them perennial kings of the category. Like their sedan sibling, the M5, however there is a bit missing when it comes to audible enjoyment. While in stock trim the exhaust note is respectable, it is held back from unleashing its true glory in the name of refinement and respectability. Dinan brings forth an exhaust upgrade that retains both these important characteristics but also allows the full chorus of all 8 cylinders to surge through the system and display their vocal talents. With Dinan the beast has found its bark… and it is glorious.

Manufacturer's Warranty — Dinan

Manufacturer's Warranty — Dinan
Dinan warrants its Performance Products to be free from defects in materials and workmanship, and the term depends on the car. If the vehicle is still covered by the original manufacturer's new car limited warranty (4 years or 50,000 miles — 80,000 km in Canada — from first retail sale; US and Canadian specification vehicles only), the Dinan part is covered for the remaining term of that new car warranty, and an Authorized Dinan Dealer repairs or replaces the defective Dinan component without charge for parts or labor, including any original manufacturer component directly affected by it. If the car is out of its new car warranty, Dinan Performance Products carry a 2-year, unlimited mileage warranty from the date of original purchase; labor is reimbursed at the dealer's standard flat-rate, but repairs to affected original manufacturer components are not reimbursed. DINANTRONICS Sport, DINANTRONICS X and DINANFLASH handheld units are 1 year, unlimited mileage; refurbished products are 90 days; and racing-only parts are guaranteed against defects in workmanship only — they are not warranted against wear or failure and may affect the BMW factory and emissions warranty. Dinan's warranty is transferable when the vehicle it was installed on is sold. A lawful invoice as proof of purchase is required, and the defective part must be returned to Dinan for verification before any adjustment. Not covered: return shipping, towing and rental car charges; unauthorized modification of a Dinan part, or damage from using other manufacturers' products alongside Dinan systems; non-DCT clutch assemblies, brake rotor warp and friction materials; maintenance items such as spark plugs, filters, lubricants, fluids, coolant, drive belts and light bulbs; negligence, abuse or improper installation; engine damage from altering Dinan's original boost pressure; improper or contaminated fuel; collision damage; environmental damage, flood, fire or road-salt corrosion; and any vehicle operated in a competitive event or subjected to aggressive track conditions. The warranty is void if the VIN or odometer has been altered, if the vehicle was declared a total loss or salvage, or if it has been used in competition. Note that installing performance products may affect the vehicle manufacturer's own new car warranty. Because Dinan handles claims through an Authorized Dinan Dealer, if you bought it here, contact PitStopTuning and we'll file the claim with Dinan for you rather than approaching Dinan directly.
Warranty terms are set by the manufacturer and may change. Contact us if you need help with a warranty claim.
