The Flowmaster 842518 Super 10 Series muffler is designed for drivers and builders seeking an exceptionally loud, aggressive exhaust tone. Intended primarily for off-highway and race applications, this single-chamber muffler delivers the extreme sound level associated with the Super 10 Series while helping support strong exhaust performance. It is not recommended for street-driven vehicles due to its highly aggressive sound profile.

Built from durable 16-gauge 409S stainless steel, the Flowmaster 842518 is fully MIG welded to provide reliable strength and long-term resistance to typical exhaust-system heat and corrosion. Its patented Delta Flow technology is race-proven and engineered to manage exhaust flow while producing the distinctive, powerful sound expected from Flowmaster Super Series mufflers. The compact design can simplify installation where space is limited, although this universal muffler may require custom adaptation, fabrication, or additional exhaust components for proper fitment.

This Flowmaster Super 10 muffler features a 2.5-inch offset inlet and 2.5-inch offset outlet for compatibility with appropriately sized exhaust tubing. It is suitable for a range of custom exhaust projects and is listed for applications including select 1982–1983 Oldsmobile Custom Cruiser models and 1982–1986 Pontiac Bonneville models. Verify the vehicle, exhaust layout, tubing configuration, and intended use before installation. Professional installation is recommended to ensure secure mounting, correct alignment, and leak-free connections.
