Jacob ★★★★★

Dropped the XL Series muffler on my '79 F-100 and the tone is exactly what I wanted—deep but not drone-y at highway speeds. The perforated tubing and baffle combo really cuts that annoying resonance without choking the flow.

Robert ★★★★★

Finally got around to installing this on my truck and the difference in sound quality is immediate. The multi-chamber design really does cut the drone at highway speeds without restricting flow.

Mia ★★★★★

The perforated tubing and baffles really do the trick—it killed the drone on the highway without choking the flow, and the oval 4x9x18 shape tucked under my truck bed with zero clearance headaches. Sound is deep and aggressive, exactly what I wanted for daily driving.
