Compact size is perfect for applications with limited space. Reversible design for installation flexibility. The 401343 resonator is ideal for taking a loud system down a bit. It can be used alone in a single exhaust system or in pairs in a dual system. 100% welded construction for strength. It features a straight through performance design and is constructed of T-304 stainless steel for high durability and includes notched inlet and outlet necks to allow for easy installation using 1" wide band clamps (clamps not included). It utilizes continuous-filament fiber (CFF) acoustic material for sound control. As with all Borla® mufflers and resonators, it is made in the USA and is covered by the Million-Mile Warranty.
