Quiet, Normal, Sport, and Race modes are worth keeping, so we built the X F1 Pipe around them.You keep the factory mode-select exhaust but change the tone underneath it. The long X design gives the Mustang a smoother, higher-pitched sound while helping clean up the raspy, truck-like character the factory system can have.It's for owners who want a better exhaust note, not just more noise. The SPE X F1 Pipe is cut-to-fit, reuses the factory clamps up front, includes rear clamps, and installs with basic tools.
