Had the Roush cat-back system installed on my 2017 F150 and it was a bit louder than I thought it would be and a bit as called here bumble bee sounding. I had the Flo-Pro 3” Resonator installed with a flex coupling to insure no vibration and WOW, what a difference. My truck sounds great now. The exhaust shop I had it installed at tried to talk me into a regular resonator but I told him I wanted the Flo-Pro. After the install, even the installer thought it sounded great. It is the PERFECT combo with a Roush exhaust in my opinion.
