What kind of sound can I expect from this muffler?

This MagnaFlow muffler is designed to produce a smooth, deep exhaust tone. The straight-through design allows for less restriction compared to chambered mufflers, contributing to a more pronounced sound.

What does 'offset/offset' mean for the inlet and outlet?

Offset/offset means that both the inlet pipe and the outlet pipe are located on the same side of the muffler's body, but they are not centered. This configuration is common for fitting into specific exhaust system layouts.

Is any hardware included for installation?

This product is the muffler itself. Installation hardware, such as clamps or hangers, is typically sold separately and may be required depending on your vehicle's exhaust system.
