The Flowmaster Super 10 Series muffler, part number 842515, is designed for drivers and racing enthusiasts who want an exceptionally loud, aggressive exhaust tone. Intended for off-highway and competition use, this universal muffler delivers a powerful sound profile while helping support strong exhaust performance. It is not recommended for street-driven vehicles due to its extreme sound level.
Built with durable 16-gauge 409S stainless steel, the Flowmaster Super 10 muffler is fully MIG welded for long-lasting strength and corrosion resistance. Its single-chamber design incorporates Flowmaster’s patented Delta Flow technology, a race-proven internal configuration engineered to improve exhaust flow and provide the aggressive performance character associated with the Super Series. The compact case design helps simplify installation where space is limited.
This universal muffler features a 2.5-inch center inlet and 2.5-inch center outlet. Some vehicle-specific adaptation, including additional piping, hangers, or welding, may be required for proper installation.
