Dinan Performance Products We Offer at Excluservice
Our shop in Rockville, MD installs a wide range of Dinan BMW performance parts, all professionally integrated by our experienced technicians:
✔ ECU & Software Tuning
Dinan’s Engine Performance Tunes (DINANTRONICS) safely increase horsepower and torque using software that maintains factory fail-safes and diagnostics. These tunes are smog-legal in many states and deliver smoother power curves and improved throttle response without the risks of generic tunes.
✔ Free-Flow Exhaust Systems
Crafted from 304 stainless steel, Dinan exhausts reduce backpressure and improve exhaust tone while maintaining comfortable sound levels. Available in both axle-back and full systems, these units deliver performance gains with a signature Dinan growl.
✔ Cold Air Intakes
Dinan Cold Air Intake Systems improve airflow to the engine by drawing in cooler, denser outside air. This results in increased power and improved throttle response while preserving MAF scaling for proper fuel trim.
✔ Performance Suspension Systems
Improve your vehicle's handling with Dinan's carefully balanced suspension upgrades, including springs, shocks, strut tower braces, and adjustable sway bars. These upgrades reduce body roll, sharpen cornering, and maintain ride comfort—making them ideal for spirited daily drivers.
✔ High-Performance Intercoolers & Turbo Upgrades
For turbocharged BMWs, Dinan offers intercooler upgrades that improve heat dissipation, reduce heat soak, and sustain consistent power output during aggressive driving. Select models also offer Dinan-specific turbocharger kits for significant horsepower increases.
✔ Aesthetic and Functional Add-ons
From carbon fiber engine covers and pedals to short shift kits, Dinan enhances both the look and feel of your BMW. Every component is designed to complement the OEM design and driving dynamics.
Dinan Warranty Coverage
Dinan offers one of the most comprehensive warranties in the performance aftermarket. When installed at an authorized facility like Excluservice, Dinan parts come with:
- Factory Matching Warranty: If your BMW is still under its 4-year/50,000-mile warranty, many Dinan parts are covered to match that original coverage when properly registered.
- Standalone Warranty: For vehicles out of factory warranty, Dinan parts come with up to 2 years coverage, protecting you against manufacturing defects.
