Description of Lawson Industries 77752 INSYNERATOR Performance
High flowing three chamber design. Made for large displacement engines (Trucks/SUVs). Reduces interior resonance ("cab drone"). Increases horsepower, torque and MPGs. Deep performance sound.
Sounded great even on a 4 cylinder Nissan 2.5 QR25DE but too loud. A little buzzed, but as I said, the noise in the cabin did not appear. Came back because it was too loud for my liking.
