Corsa Cat-Back Exhaust for 2007+ 335i models
Reflective Sound Cancellation
technology for the 335i
CORSA is one
of the largest automotive and high-end marine exhaust tuning
companies in the USA with engineering and manufacturing facilities
in Ohio and a patented, proprietary technology called Reflective
Sound Cancellation™. CORSA consults to General Motors, Ford,
and Daimler-Chrysler.
The result of the UUC and CORSA partnership is a drone-free
exhaust system, delivering a pleasant sound at idle and cruise and
a muscular roar at high rpm.
Reflective Sound-Cancellation™ (RSC™) -
a non-electrical noise control system without the complication of
incorporating the use of electronics or speakers. Essentially,
engine sound (pressure) waves are reflected in passages inside the
muffler to cancel out unwanted sound waves. The result is a "tuned"
muffler that "cleans up" the noise without eliminating the pure
sound of power associated with a high-performance vehicle. Using
this Corsa technology, the stainless steel Corsa Performance line
of mufflers are tuned to eliminate passenger cabin resonance and
produce just the "right" sound. .
The Corsa Performance muffler design does not use conventional
packing materials, and provides a totally un-restrictive exhaust
flow for maximum power output.
The RSC335 is fully emissions-legal
in all 50 states.
There is no effect
whatsoever on emissions and there will not be any "Check Engine"
warning lights.
"Best in class" build quality, made
right here in the USA!
Construction enhancements include
100% mandrel-bent pipes, 4" PRO-series tips, and
TIG-welded seams.
SOUND LEVEL
CERTIFICATION
Many
statutory bodies around the world currently mandate that vehicles
comply with stationary exhaust noise tests specifications -
Generally based upon the "SAE J1169 Measurement of Light Vehicle
Exhaust Sound Level under Stationary Conditions". California and
various other states now have legislation that makes exceeding this
limit an offense, resulting in a "fix it" ticket and required
testing certification.
The test involves positioning a type 1, SIA compliant ANSI S1.4 -
1983 noise level meter, specifically as illustrated in the diagram
to the left. Positioning is relevant, the tests are extremely
specific in their scope and must be conducted under controlled
conditions.
RSC335 has been certified to meet the SAE J1169 sound test for
95dB noise limits and is therefore legal in the many states that
use this test as their reference.
