Review on 🚗 Flowmaster 52571 70 Series Muffler - 2.50 Offset IN / 2.50 Center OUT - Mild Sound, Black: Optimize Your Vehicle's Performance with Flowmaster's Superior Exhaust System by Alex Solano

This is a single input, single output on a 2003 Toyota Tundra V8. This gives me EXACTLY what I wanted. A little more rumble without having to put up with an intrusive hum. I understand it. If you're looking for a loud rumble when you turn the car on, this isn't it. But if you want a nice quiet rumble and a feeling of increased power under acceleration, then this is exactly what you need. I love it. Made for big cars, it's really great. I support it!
