Flowmaster super 10's, removed the NPP.

After much research and listening to every sound clip I could find, I went to a local shop and the guy suggested the Flowmasters. I was definately apprehensive because of the drone but I've always used them so I took a chance. Dual Flowmaster Super 10's with dual 4 inch flowmaster tips. Wow was he right, what a beautiful sound. There is some minor drone between 1700 and 2000 rpm when your foot is on the gas but the sound is worth it and all for $600.00 (price will vary by region, it's expensive in South fla.) I almost went with the Borla but ended up saving a grand. If anyone needs a new factory NPP system mine only had 500 miles on it. I'll post some sound clips when I make them.

My 2018 came with the dual NPP exhaust. Too quiet for me. I bought the flowmaster american thunder 817746 system. So far, so good.

Did you eliminate your NPP functionality all together? When you have time, please post a picture. Thanks!

FM Super 10s are the best I have heard so far. Please do some drive bys shifting gears and winding it out.

I did the same but I kept my NPP valves with 10 series and have very minor drone.

An update to all:
Today, I noticed that my Flowmaster American Thunder 817746 would squeak every time the valves would open and close. So, I pulled the infamous Fuse 51 and no more squeak. Valves stay open all the time. Has anyone else pulled the Fuse on their aftermarket dual mode NPP exhaust system?
