The Dinan X-Pipe for the F95 X5M and F96 X6M introduces a more aggressive tone and increased volume over the stock system. Coupled with the associated Dinan exhaust, the sound is further enhanced into a smoother, fuller, and more aggressive growl that perfectly encapsulates the dynamic nature of the V8 powered SAV's. This full mid-section kit removes the hydro-formed factory center section, including the resonator, and replaces it with larger 3.25" T304 stainless steel tubing for freer flowing capabilities. In place of the 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 found in stock systems. Along with the inherent benefit of increased volume by removal of the resonator, the Dinan X-Pipe for the F9x X5M/X6M produces a louder, smoother, and fuller exhaust note. Features: Smoother, louder and sportier sound 83mm tubing replaces stock 80mm tubing for free flow Deletes resonator between catalyst and rear muffler for increased volume Includes X-pipe crossover made from mandrel bent tubing for minimum restriction 100% 304 stainless steel construction Factory-like fitment with included mounting hardware NOTE: Only confirmed to fit with the Dinan Free Flow Axle Back and stock exhaust systems. Fitment with other axle back units is not guaranteed. No cutting is required when paired with the Dinan Free Flow Axle Back system.

The Dinan center pipe replaces the resonator in the M235i exhaust. By deleting resonators you can gain a little more volume from the exhaust. This is especially good if you're a fan of the stock exhaust sound and just want to hear more of it. And with less restriction there is a slight horsepower and torque gain as well! This pipe fits best with the Dinan Free Flow rear muffler but will fit on the stock exhaust too.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. 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. The resonator-delete pipe is worth 1 point towards your Dinan badge.

This item fits the following BMWs:
2014+ F22 F23 BMW M235i M235iX

Get that aggressive tone fitting for the M3 and M4! The Dinan High Flow X-pipe for the F80/F82 M3/M4 elicits an aggressive sound that is sure to capture the ear of all bystanders and delivers the aural recognition that all M3/M4 owners deserve. Coupled with the associated Dinan exhaust the sound is further perfected into an aggressive growl that harkens back to the Dinan E9x M3 racing middle exhaust. Rightly so, as the same custom 'X' that was used in that application is implemented on the new F8x chassis for that perfect mix of exotic undertones and raw aggression. Unlike a stamped x-pipe that is so common in the marketplace the Dinan 'X' is thoughtfully designed for maximum flow characteristics and by itself is a work of art. The Dinan X-Pipe removes the factory center section after the secondary catalytic converters, including the large resonator. In its place Dinan introduces straight through mandrel bent 2.75" T304 stainless steel tubing and the custom 'X' for better flow, and an improved throaty sound. In addition, the kit comes complete with mounting hardware, OE quality clamps, and flanges, for simplified installation. NOTE: Since a resonator is deleted there is potential for increased cabin noise associated with the Dinan High Flow X-Pipe. Features: Deletes both resonators, between catalyst and rear muffler. Stock hydro-formed 65mm tubing is replaced by 2.75" (70mm) mandrel-bent tubing for free flow. Includes X-pipe crossover made from mandrel bent tubing for minimum restriction, unlike stamped X-pipes 100% 304 stainless steel construction. Bolt-on installation. Includes mounting hardware.
