The compact diameter of these mufflers make them great for both classic and late model cars with ground clearance issues. Sound is attenuated with the Borla(r) patented Multicore design and high-temperature continuous-filament fiber (CFF) acoustic material, without losing any horsepower or torque. 100% welded construction for strength. Built with T-304 stainless steel they have unequaled durability and great looks that you can polish to a mirror like finish, if desired. Best of all, it's made in the USA.
