"Racers are burning the
packing out of some mufflers
we've seen," said Adair. "That
burning causes the volume
of air inside the muffler to
change over time, which can
influence performance, so
Gibson made the decision
not to use packing to keep
performance airflow consistent."
Gibson's MWA design is their
latest techology, and was
unveiled at the 2015 SEMA
Show. It is a straight-thru
muffler that promotes exhaust
gases to flow at the highest
rates, flowing only three cfm
less than a three-inch straight
pipe. Gibson claims it improves
power potential while keeping
interior drone to a minimum.
Richard Waitas senior manager
at Magnaflow has a similar
opinion of what mufflers do
RACING HEADER DESIGN
AND LENGTH IS CRITICAL
BUT IT MUST ALSO FIT
WITHIN THE CHASSIS.
THIS IS WHY MOST ARE
CUSTOM-MADE FOR
EACH APPLICATION.
