The FVD Brombacher sound version muffler for the 981 and is one of the most technically advanced systems for Porsche to date. Our entire “Brombacher” line of exhausts is manufactured to our specifications by M Exhaust, GmbH in Germany as is this muffler for the 981. The benefits of this muffler are 3 fold, you can pass emissions with ease, you don't need to run a software file (for those who are concerned about warranty) and you can have more power without drone!!

We noted a + 11 crank hp & + 10 crank torque gain, predominantly in the mid and top end. The increase in mass and velocity of exhaust flow through the specially built muffler internals produces a strong, linear; firing-order dominated true flat-6 Porsche sound.

In addition, each of our exhaust products have been extensively tested on both a chassis and engine dyno as well as logged thousands of miles on both the street and at the track. All this research, development and testing ensures maximum horsepower gains throughout a broad power band; all while maintaining reasonable sound levels for the street and provide a distinct, sporty exhaust note that is purely Porsche.
