MIA's Description

The SLP Loud Mouth II Universal 2.5" Inlet/Outlet Bullet-Type Mufflers (MPN: 31064) are designed to replace restrictive OEM mufflers, offering maximum exhaust flow and a loud, domineering exhaust note. These "bullet" style mufflers feature a straight-through design for virtually no restriction. Constructed from polished 304 stainless steel, they are built for durability. The inner core is ceramic-wrapped and perforated to minimize high-frequency noise and in-car resonance. With a 2.5-inch inlet and outlet, these mufflers can be welded or clamped into an existing exhaust system. Each muffler has an overall length of 18-3/16 inches and a 4-1/2 inch body diameter. Sold as a pair.
