The muffler was professionally installed by an exhaust shop. Two inlet and two outflow pipes, 2017 Tundra. At idle a nice tone, put your foot on the accelerator pedal and hear it. I added a K & N air filter for better air flow front end and the back pressure reduction is sweet.

Looks like somebody dropped my box and dented my muffler. Looks like ups dragged the box with a chain. Flow master has good customer service over the phone. I would buy again from them.
