No Drone -
This is what sets us apart from other
RSC™ technology eliminates "problem" frequencies that cause interior drone/resonance at cruising speeds.
Improved Horsepower And Torque - Patented
non-restrictive Straight-through design reduces back pressure
and frees up additional power.
Great Performance Sound - Patented RSC™
technology allows CORSA to "target" and "eliminate" problem
sound frequencies without "muffling" the rest of the sound spectrum.
Potential For Better Fuel Economy -
Less back pressure and more power means your engine functions
more efficiently and that translates into better fuel economy (if you can keep your foot out of it).
Premium 304L Stainless Steel Construction
- Our systems not only look great but they stay looking great!
Even our tips are a jewelry quality, highly polished 304 stainless steel. 304L won't rust (even on the surface)
like other inferior stainless steel products. And, in most cases our system will outlast your vehicle (Ok, maybe not yours).
Limited Lifetime Warranty -
The combination of 304L stainless steel
construction and the fact that our systems
don't use cheap easily degraded packing materials means they'll last and last.
Included All Necessary Hardware And Full Color
Instructions - Our systems come with
top quality TORCA Clamps
and instructions that feature actual full color photos to make your install a breeze.
50 State Emissions Legal -
Since our systems are all designed to install
rearward of the factory catalytic converter
there are no emissions hassles. Just bolt it on and go.
Handcrafted In The USA - That's right. Our systems are hand-built right here in America!
CORSA uses its patented Reflective Sound Cancellation™ (RSC™) technology to eliminate low frequency resonance while minimizing backpressure. Sound waves are reflected within the muffler case, producing a cancellation wave effect-with no flow restriction and without electronic devices. The RSC™ design features a pipe running straight through the muffler, incorporating a full 360-degree air gap and allowing sound pressure waves to escape. The waves are channeled and then returned to the gap 180-degrees out-of-phase, canceling specific sound frequencies. All that remains is the clean, crisp sound of performance.
here shows a typical (but simplified) sound profile of a vehicle's
exhaust sounds produced at cruise speed. Note the high amplitude of
the base (low) frequencies between @ 70Hz and 180Hz, but especially
at the 130Hz range where the amplitude (power level) of the
frequency becomes great enough to surpass the threshold where drone
or resonance is produced. This is what causes that
annoying/uncomfortable hum or roar inside your vehicle.
Figure 2 shows a representative comparison of the sound attenuation ranges of the two most common muffler designs on the market today; 'packed' or dissipative (blue graph) and 'baffled' or sound chamber/tank volume (green graph), versus the CORSA RSC™ technology (purple graph).
