To achieve desired sound volume and tone worthy of the G87 M2 the tubing was enlarged to 76mm (vs 70mm stock) to allow freer flow, and reduce backpressure, throughout the entirety of the system. The larger piping gives way to multiple pathways as it nears the rear of the vehicle -- the choice of which is utilized determined by the factory exhaust valves which are retained. When valves are closed, flow is directed into the Dinan muffler, where absorption and reactive technologies are used, and exit out the two inner tips. This limits noise during low-speed driving and produces a more subdued, albeit deeper, and agreeable note. However, when the valves are open during high-load conditions the bulk of the gases bypass the muffler altogether for a near straight pipe design and maximum aural enjoyment to be achieved. It's the perfect marriage for all tastes and allows civility or impassioned aggression depending on what the situation demands. The combination is one Dinan has deemed fitting for the marques signature performance models that cater to the tasteful enthusiast who demand the best for all situations.

DINAN FREQUENTLY ASKED QUESTIONS
HOW DO I CONFIRM A DINAN PART FITS MY VEHICLE?
Start with the year, make and model selector, then confirm the chassis code, engine, drivetrain and any application notes on the product page. BMW and MINI models from the same year can use different engines or hardware. If anything is unclear, contact FI Performance with your VIN and the Dinan part number before ordering.
DO CHASSIS CODE, ENGINE AND FACTORY OPTIONS MATTER?
Yes. Dinan fitment can depend on chassis generation, engine code, production date, transmission, rear- or all-wheel drive, factory suspension, brake package and other equipment. A model name alone is not always enough to establish fitment.
DO DINAN INTAKES AND AIRFLOW PARTS REQUIRE TUNING?
Many Dinan intake and airflow upgrades operate safely without additional software, while some applications achieve their advertised results only when paired with compatible tuning or supporting hardware. Follow the requirements listed for the exact part number and vehicle application.
WHAT SHOULD I EXPECT FROM A DINAN EXHAUST?
Dinan exhaust systems are designed to add a deeper, more purposeful tone while maintaining refined street manners. Sound level, cold-start volume and cabin presence vary by vehicle, exhaust section, drive mode and other installed components. Review the exact product description before ordering if sound level is a primary concern.
WILL DINAN SUSPENSION OR CHASSIS PARTS CHANGE RIDE QUALITY?
They can. Springs, dampers, sway bars, braces and related chassis parts may produce a firmer or more controlled ride depending on the combination and settings used. A professional alignment is recommended after installing components that alter ride height or suspension geometry.
WHAT IS REQUIRED AFTER INSTALLING DINAN BRAKE PARTS?
Brake components must be installed to the vehicle and product specifications. New pads and rotors should receive the correct bedding procedure, and the system should be inspected for proper operation before normal driving. Brake work should be completed by a qualified technician if you do not have the required tools and experience.
DO DINAN ENGINE AND TUNING PRODUCTS REQUIRE SPECIAL INSTALLATION?
Requirements vary. Some inline modules are designed for straightforward sensor connections, while software, turbochargers and other advanced engine upgrades may require special tools, programming, supporting modifications or professional installation. Use Dinan's instructions for the exact part number and do not substitute instructions from another application.
HOW DO I CHOOSE THE CORRECT WHEELS, SPACERS AND HARDWARE?
Confirm wheel diameter, width, offset, center bore, brake clearance and tire fitment for the vehicle. Spacers must use the correct bolt pattern, hub fitment and matching extended hardware where required. Never stack wheel spacers, and always follow the specified torque procedure and recheck schedule.
HOW ARE DINAN EXTERIOR AND INTERIOR PARTS INSTALLED?
Installation ranges from direct replacement to adhesive bonding, trimming or removal of factory panels. Dry-fit cosmetic parts before final installation and follow the supplied surface-preparation and curing instructions. Professional installation is recommended for carbon-fiber pieces or any part requiring permanent modification.
ARE DINAN DRIVETRAIN AND SHIFTING UPGRADES STREET FRIENDLY?
Dinan designs many drivetrain and shifting upgrades to improve response and driver engagement without sacrificing everyday usability. Increased shift effort, vibration or mechanical feedback can still occur depending on the part and vehicle. Check the product notes for the expected change before purchase.
ARE ALL DINAN PERFORMANCE PARTS EMISSIONS LEGAL?
No. Emissions status is part- and application-specific. Some products are 50-state legal, some are not legal for sale or use in California, and others may be intended only for competition vehicles. Review the emissions statement and any CARB Executive Order listed for the exact part and vehicle before ordering or installing it.
WHO SHOULD INSTALL DINAN PERFORMANCE PARTS?
Installation difficulty varies by category and application. Always review Dinan's part-number-specific instructions first. Safety-critical, software, engine, suspension, brake and permanently bonded components should be handled by a qualified performance shop when the procedure exceeds your tools or experience.
WHAT WARRANTY APPLIES TO DINAN PRODUCTS?
Warranty coverage varies by product, vehicle and installation. Dinan states that its performance products generally carry a two-year, unlimited-mileage warranty, while certain qualifying products or applications may have different or factory-matching coverage. Warranty does not cover problems caused by improper installation, misuse, misapplication, modification or neglect. Review the current Dinan warranty terms for the exact product before purchase.
