Flowmaster 40-Series Delta Flow mufflers

deltaflowFeaturing a two-chamber design

94244140-Series mufflers incorporate Flowmaster’s patented “Delta Flow” technology.  The “Delta” deflectors result in increased scavenging for better performance and reduced interior resonance over the standard 40 series with a nice growl outside the vehicle.  Flowmaster 40-Series Delta Flow mufflers sound great on late model performance cars with catalytic converters, but work equally well on all applications.  They are available in in either aluminized steel or 409S Stainless for harsh weather applications.   Both are fully MIG-welded for maximum durability.  These mufflers are 4″ Thick x 9.5″ Wide x 13″ Long with inlet/outlet sizes available from 2″ up to 3″ and a variety of inlet/outlet positions.
