Dinan sport mufflers are designed to compliment the F3x and not overpower the driver and passengers with harsh tones. Dinan engineers their exhausts to sound great and be a natural fit to the character of the car as well as produce more power and torque. Dinan uses only 304 stainless steel in their systems for the maximum corrosion protection. Simple bolt in installation frees up 4HP and 3 lb/ft of TQ.

When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere.

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.

Looking to elevate the external acoustics of your G8x but want to upgrade in stages and/or not break the bank? The Dinan Middle Exhaust for the G80 M3 is and G82/G83 M4 introduces a more aggressive tone and an increase in volume over the stock system while retaining the factory muffler at a budget friendly price point. Should the desire for more arise however, it can easily be paired with the matching Dinan axle back exhaust for further aural enhancement and a more aggressive growl. It is a union that boasts a bold, yet sophisticated, exhaust note that neither can fully achieve on their own. This middle exhaust itself removes the hydro-formed factory center section from the secondary catalysts back to the axle back, including both resonators, and replaces it with larger 3-inch T304 stainless steel tubing for freer flowing capabilities. In place of the forward factory resonator, Dinan incorporates a beautifully crafted X-pipe made from mandrel-bent tubing for minimum restriction, unlike stamped X-pipes which are commonplace in the market. This hand-made 'X' is not only the focal point of the system in terms of aesthetics but also the star when it comes to the effects on the sound. Promoting even flow to both banks of tips, the 'X' removes unwanted nuances in sound caused by uneven exhaust flow that is present in the stock system. Along with the inherent benefit of increased volume by removal of the resonators, the Dinan X-Pipe for the G8x M3/M4 produces a louder, smoother, and fuller exhaust note that will deliver smiles time and time again. Features: Smoother, louder, and sportier sound 76mm (3-inch) tubing replaces stock 70mm (2.75-inch) tubing for free flow Deletes resonators between the secondary catalysts and rear muffler for increased volume Includes X-pipe crossover made from mandrel bent tubing for minimum restriction 5-pounds lighter than the stock mid-section (Stock: 22-pounds vs. Dinan: 17-pounds) 100% 304 stainless steel construction Factory-like fitment with included mounting hardware
