SPD Performance Upgrade
Our HX Series Helmholtz resonated muffler upgrade is the last component to the ultimate Gen2 Raptor or HO Limited F-150 exhaust system.
Built for the F-150
By targeting and neutralizing specific drone frequencies, you will still enjoy the exotic exhaust notes of the equal length without the drone. When combined with our equal length trombone (RDFR20EL ) , there is no better sounding Gen2 Raptor exhaust! A x p ipe was designed in to blend the exhaust tones after the equal length trombone.
HX Series mufflers are a straight through design, with no reductions or chambers inside the muffler which guarantees ultimate flow and performance. The main purpose of the Helmholtz resonator on this exhaust system is the in-cab noise/drone reduction without making the exhaust too quiet. Our HX Series Helmholtz resonated muffler upgrade is the last component to the ultimate Gen2 Raptor or HO Limited F-150 exhaust system.
