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.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preference. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

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
