The parts are well built, fit exactly as intended, and weren’t difficult to install. The 5-inch straight pipe gives the truck a sound I absolutely love.
Completely satisfied.
The muffler is compact, flows well, has a deep tone, and produces no drone at highway speeds.
Muffler eliminated cab drone while keeping a strong exhaust note. Good balance for daily driving.
The Optimal Flow 5-inch muffler arrived quickly and looks well made. It seems like a good balance to keep noise reasonable when towing. Planning to pick up the remaining components soon.
