Varitune Adjustable S.S. Muffler 3in Dia.

The BBK Performance Varitune Adjustable Stainless Steel Muffler 3-inch Diameter (SKU BBK31035) is a universal performance exhaust muffler designed for vehicles requiring a 3-inch offset inlet and outlet configuration. Built from stainless steel construction, this muffler features an 18 x 10 x 5-inch oval body and extends 22 inches in total length, delivering corrosion resistance and durability for both street and performance applications. The adjustable Varitune design allows tuning of exhaust tone and backpressure characteristics across varied engine speeds and load conditions.

The 3-inch diameter inlet and outlet design accommodates most aftermarket exhaust systems with standard 3-inch piping, simplifying installation on vehicles with existing 3-inch exhaust setups. The offset inlet and outlet orientation provides clearance flexibility for different vehicle chassis and suspension configurations. The oval body geometry optimizes internal chamber volume and flow characteristics, balancing acoustic performance with minimal backpressure. Stainless steel material resists rust and corrosion from moisture, road salt, and high exhaust temperatures, extending muffler service life in harsh operating environments.

This muffler suits automotive enthusiasts, performance tuners, and builders upgrading exhaust systems on vehicles where a universal 3-inch muffler with adjustable acoustic characteristics fits the application. The adjustable Varitune technology appeals to users seeking tone customization without replacing components. Weighing 11.3 pounds, the muffler installs as a single component into existing exhaust runs. The universal design and stainless construction make it suitable for street vehicles, weekend drivers, and applications where durability and sound tuning flexibility are priorities.
