Arguably THE BEST modification for your B46/B48. This muffler delete sounds too good to be a 4 cylinder! The combination of B48 and muffler delete surpasses all sound expectations from a 4-cylinder! Impressive direct-fit solution. With this new muffler delete you can transform the sound and driving experience of your 330 or 430. A simple installation that can be completed with hand tools gives you the ability to take your car to the next level at home in your garage!

Incorporating their distinctive design principles, this exhaust produces a commanding, deep tone, revealing the bold personality of the revolutionary line of 4-cylinder turbo engines. Leveraging the factory valve control, the Turner axle-back ensures an exciting sound during acceleration, seamlessly blending the high-performance sound with daily driving convenience. Crafted from 1.25mm wall T304 stainless steel, Turner's exhaust boasts superior durability, corrosion resistance, and aesthetic appeal.

Upgrading the sound:

This exhaust allows you to turn up the volume and let the 4 cylinder boast its smooth and hearty exhaust tone. Let's be honest, what's the point of owning a f chassis if you're not going to upgrade the exhaust? Turner's signature muffler design allows you to transfer the exhaust valve from your factory system directly onto your new Turner system. The Turner exhaust signature muffler design allows for two flow paths that change both tone and volume. With the vehicle in eco or comfort mode, the valves remain closed, with the closed valves the exhaust system allows the gasses to flow through the muffler toning down the volume and giving a more refined exhaust note. While in driving modes sport or sport+ the valve opens and the flow path changes to a "straight flow path" essentially turning into a straight-piped exhaust for the least amount of restriction and the most amount of B48 sound!

The Dinan sport muffler is designed to compliment the 328/428 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. Dual 3.5" stainless tips engraved with the Dinan logo fill out the rear valence (choose either polished or satin black tips). Annoying highway drone has also been engineered out of the system. Dinan uses only 304 stainless steel in their systems for the maximum corrosion protection. This system replaces the factory rear mufflers at a pre-determined cut point on the stock exhaust, which makes for an easy installation and you can reinstall your original mufflers using factory hardware. Detailed installation instructions are included.

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 Dinan sport muffler is worth 3 point towards your Dinan badge.
