BMW F97 X3M & F98 X4M Pre-LCI Single Midpipe & Under Brace In Stainless Steel

Welcome to BMW S58 Single Mid Pipe for the BMW F97 X3M & F98 X4M pre-LCI, or in other words, the solution to the F9X sound problem. Enthusiasts have wanted to find a solution to the buzzy and raspy sound these cars produce from the factory. Since these cars were released, we all knew there was a world-class sound lying under all the rasp. Our mission has been to find this hidden sound and allow all BMW F9X owners to enjoy it. It's time to make the X3M and X4M sound like they always should have.

• Extended under brace
• Much deeper exhaust tone and reduced rasp which is typical of the S58
• 100% TIG welded
• Highest quality 304 stainless steel
