Going beyond its Foundation counterpart, the Dinan Experience packages address not only the engine but also the chassis for a complete solution in the form of a wholly tuned Dinan vehicle. While adding power modifiers is often the go-to path when beginning the modification journey, it does not fully consider what makes the car infinitely more enjoyable in scenarios outside of WOT pulls. With the addition of suspension upgrades integrated alongside the power adders, the vehicle is transformed into something more than just the sum of its parts. It's a comprehensive answer to delivering additional technical capabilities in the form of increased engine performance and better handling along with improvements to aesthetics (looks and sound) in a package designed with reliability and safety in mind. This union of power and handling modifications results in a true OEM+ experience - the Dinan Experience. Includes Dinan Exhaust Dinan Intake Dinan Turbo Inlet Dinan Strut Braces Dinan Pedal Cover Set Dinan Badge Features Smiles per gallon instantly multiplied Guaranteed component compatibility and seamless integration 10% price savings when compared to buying the same components a la carte Maximum gains of +9 HP and +8 lb-ft of torque (Exhaust +Intake) Smoother, louder and sportier sound (Exhaust + Intake + Turbo Inlet) Computer-controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions (Exhaust) 4 pounds lighter than the stock for an improved power-to-weight ratio (Exhaust) Reduced intake restriction for greater flow that allows increased turbo efficiency and greater power potential on modified builds (Intake + Turbo Inlet) Improved throttle response (Intake + Turbo Inlet) Increased chassis rigidity with decreased flex during cornering for improved handling and performance (Strut Braces) Elevated and stylish high-performance look to the interior (Pedal Pads) Every Experience Package instantly qualifies for the Fabled Dinan deck lid badge

The Dinan Exhaust Valve Remote lets you override the factory exhaust valve operation and fully open (or close) the valve at the press of a button. Directly compatible with 'F' and 'G' chassis BMW's using a single electronic valve as well as 3rd generation MINI's, the Dinan Exhaust Valve Remote Kit is robust in its potential applications.

Tested and compatible valve actuators include BMW P/N's 18307851568, 18308686640, 18308632154, and 18308623424. Features: Opens the factory electronic exhaust valve with the push of a button.

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. Utilizing factory cut points and mounting mechanics this Dinan exhaust system is a straightforward install with fitment like you would expect from the manufacturer. 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. 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. Max HP Gain4 @ 6600 RPM - Max Torque (lb-ft) Gain3 @ 6600 RPM Features: Enjoyably louder, sportier sound Drone abatement technologies used to reduce cabin resonance Dual 4" (102mm) double-walled, black ceramic coated 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
