Flowmaster 2.5 IN(O)/2.5 OUT(O) Super 10 SS Muffler

Super 10™ Series 409S stainless steel, single chamber mufflers. Intended for customers who desire the loudest and most aggressive sound they can find.

These mufflers utilize the same patented Delta Flow® technology that is found in Flowmaster's other Super series mufflers to deliver maximum performance. Constructed of 16 gauge 409S stainless steel and fully MIG welded for maximum durability. Super 10 Series Stainless Steel - 2.50 Offset In / 2.50 Offset Out - Aggressive Sound Universal Muffler - Some adaptation may be required.

• Race-Proven Delta Flow Technology
• 409S Stainless Steel Construction
• Compact Size For Easy Fitment
• Super 10 Sound Level

The Flowmaster Super 10 Series muffler, part 842518, is designed for enthusiasts seeking an exceptionally loud and aggressive exhaust tone. This single-chamber muffler uses patented Delta Flow technology to support strong exhaust flow and race-proven performance. Its Super 10 sound level is intended for off-highway and competition applications and is not recommended for street-driven vehicles due to its extreme sound character.
Constructed from durable 16-gauge 409S stainless steel, the Flowmaster 842518 is fully MIG welded for lasting strength and resistance to demanding operating conditions. The compact case design helps simplify installation where space is limited, while the 2.5-inch offset inlet and 2.5-inch offset outlet provide a universal configuration for compatible exhaust systems. Some adaptation may be required for proper fitment.
This universal Flowmaster Super 10 muffler is suitable for select applications, including certain 1982–1986 Pontiac Bonneville models and 1982–1983 Oldsmobile Custom Cruiser vehicles. Verify exhaust configuration and clearance before installation. The product is not CARB approved and may not be legal for use on pollution-controlled vehicles in all areas. California Proposition 65 warning applies.
