Came promptly in genuine flowmaster packaging. SOLID, heavy, Super 40 muffler. Sounds good with my 5.0. 5 stars for sound alone . Significant drone when driving around town but quiets down when cruising the highway. My setup is 3” pipe with no resonator. Single in/single out to OEM style exit. F-150 5.0

What a difference! Now my truck sounds like a truck! Reduction of RPM's at 70mph from 2200 to 2000. Mileage gain of 2 to 3+ mpg. There is a drone inside the cab while accelerating, but nothing more than pleasant sounds when at speed. Every Silverado needs one of these!

Well constructed, good quality muffler. It puts out the perfect amount of exhaust noise. It’s not too loud or too quiet, it’s just right. I love this muffler, my Truck sounds real nice.

I put this on my 1995 Ford 460 motorhome. I noticed an immediate increase in torque, power, mileage per gallon and the fact that it now sounds like a race car is awesome! The biggest difference is she can now climb any hill at speed (60-70mph) without shifting out of overdrive.

Muffler looks and sounds great. Not too loud but enough deep sound to highlight V8 on Silverado 1500. Only downside, it burns the outside paint for few days and smells terrible.

Quality product, but why in the world paint it? Love the sound but you will need to leave vehicle running outside for an hour or two to burn the paint off or it will knock your socks off while driving.
