G2X M340i M440i MidPipe w Active brace

Product Description

G2X BMW M340i/M440i Mid-Pipe

At Active Autowerke, it's not ONLY about making as much power as possible but to maximize the enjoyment of the drive. For 40 years, power has been the end result of improved performance due to our relentless desire to develop a refined, quality product. This philosophy behind our performance parts is best represented by one of the newest additions to our G2X/G3X BMW M340i and M440i collection.

The Active Autowerke M340i/M440i midpipe was engineered to add that little extra to those looking to get some more sound from the factory or after-market M340i and M440i exhausts, while also allowing for optimum flow and resonance by removing the resonator in the Y from the BMW stock midpipe. Every effort was made to ensure that the midpipe would work with the stock exhaust and enhance the sound with a deeper tone. We believe our midpipe together with our rear exhaust offers the best combination of sound and performance versus other systems on the market today. Available for both models, this midpipe gives your BMW the deep growl a car of its caliber should have had from the factory! We include our custom G2X brace to provide additional clearance for our midpipe.

PLEASE NOTE - this exhaust is midpipe intended for those who only wish to replace their stock midpipe so there needs to be a cut - all connecting hardware is provided. If the midpipe is installed at the same time as our Active Rear Exhaust no cutting is required as the entire stock exhaust can be dropped and replaced with the Active midpipe and rear exhaust.
