Dinan's PCU installs as a “piggyback unit” between select sensors and the ECU. It then adjusts these signals to achieve increased performance. It also uses the OBDII connection to provide a range of capabilities beyond mere power increase. The Dinan PCU is controlled by a user-friendly free Bluetooth app available for both iOS and Android devices. This app provides access to all the device’s potent features.

For those that wish to have options to limit the soundtrack for late night or early morning arrivals/departures, factory valve control is retained. No matter the situation the Dinan valved axle back exhaust system is the answer for the discerning enthusiast looking for performance without sacrifice. The Dinan G20 330i / G22 430i exhaust grants the B46/B48 4-cylinder improved exhaust flow by reducing back pressure, and also creates a deeper and fuller note, without any added drone or other negative side effects.. The goal of OEM+ and then some. This Dinan exhaust system is a straightforward install with fitment like you would expect from the manufacturer using factory cut points and mounting mechanics. Going from the plebeian stock dual slash cut 90mm (3.5") tips to the massive Dinan straight cut 102mm (4") ones leaves no doubt that something above and beyond is present. This is solidified by the Dinan logo laser engraved on the tips and the deep growl of the exhaust that is indisputably different than anything one would expect to hear from a base 4-cylinder turbo platform. Features: Maximum gains of +4 HP and +3 ft-lb of torque Enjoyably louder, sportier sound Drone abatement technologies used to reduce cabin resonance Dual 4" (102mm) double-walled, polished clamp-on tips with laser engraved Dinan logo Larger diameter piping for increased flow (85mm to dual 60mm vs. 85mm to dual 83mm) 100% 304 Stainless Steel construction Retains factory valve control Factory-like fitment with included mounting hardware

Dinan's 395x34mm 2-piece 6-piston Big Brake Kit (BBK) is an ultra-high-end solution for maximum stopping power. Each feature-packed solution is specifically tailored to your vehicle and provides exceptional stopping-power in a wide operating range from daily driving to professional racing. Because of this, the system provides the correct brake bias and integrates seemlessly with the ABS and stability systems which is critical under emergency braking situations. This upgrade handily out-brakes, out-lasts, and out-performs any non-vehicle application specific OEM swap kits, and rivals much more expensive top-tier systems. Whereas most systems on the market either make heavy sacrifices to either look fancy, cut weight, or cut costs, the Dinan system is designed to simply brake better, last longer, and stand the test of time!

6-Piston next-generation weight-savings billet calipers with stainless steel pistons
