Frequently Asked Questions
CORSA Performance Power-Pulse RSC™
C4 Exhaust Systems
1. How does CORSA's system compare with other C4 systems?
The test results for the leading C4 exhaust systems indicate that they all
produce approximately the same rear-wheel horsepower increase, for the most part because of the restriction caused by catalytic converters.
We see CORSA's advantage over the other systems as being able to increase exhaust flow by 42%, having the ability to produce the same
rear-wheel horsepower gain as competitive C4 systems, and eliminating unwanted in-cabin resonance which sets us apart from all the other aftermarket parts.
2. What makes the CORSA systems different or better than the other C4 aftermarket systems available?
The CORSA *Power-Pulse
RSC™ exhaust system employs a new and completely different technology called Reflective Sound Cancellation (RSC). It uses sound/pressure waves 180 degrees out of phase to cancel noise instead of internal
baffles that are restrictive or packing material that can burn-out over time. CORSA's straight-through design flows 42% more than the factory stock system without any flow restriction producing
the purest engine note available.
With CORSA's Power-Pulse RSC™ design, the driver controls the sound level with the throttle. Awesome sound at full-throttle and whisper-quiet at cruising speed. CORSA's
unique Power-Pulse RSC™ technology has been acknowledged and granted a U.S. Patent (Number 5,952,625).
3. What is included with each system?
Everything needed to complete the installation is included. Each system includes one (1) center
muffler and two (2) Power-Pulse RSC™ rear mufflers with polished 304L stainless steel PRO-SERIES 3.5 tips welded in place, two (2) headpipes, under-the-axle pipes, heavy duty CORSA TORCA clamps and complete
installation instructions. Plus CORSA's Limited Lifetime Warranty – and guarantees your CORSA muffler system for as long as you own your C4!
4. Can you describe the finish?
Every CORSA exhaust system is fabricated out of 100% stainless steel with a stylized
muffler case design providing a distinctive look. The tips are made of 304L polished stainless steel to resist rust and corrosion.
5. What about the exhaust tips?
CORSA's new PRO-SERIES 3.5 tips are featured on all CORSA
C4 muffler systems. The PRO-SERIES 3.5 tip is a double-wall angle cut design featuring internal flared edges that will grab your attention from 50 feet away and is the same tip as offered on CORSA's
fifth-generation Corvette muffler systems.
6. Is the system a bolt-on system?
It is a simple bolt-on system with no cutting, welding or modifications required, and the tips are welded in
place for perfect alignment.
7. How long does the installation take?
Using a lift, which we strongly suggest, and with basic hand tools, the removal and installation takes
about an hour to an hour and a half.
8. Does my Corvette have to be on a lift or can the installation be performed using jack stands?
Jack stands can be used if the car can be raised
safely and high enough to remove the stock exhaust system. However, it is recommended that a lift be used for safety reasons and ease of installation.
9. What tools are required to perform this installation?
Tools required include: 13mm, 15mm, and ½" and 9/16" sockets, a 9" extension (for the
15mm socket) and a no-mar hammer. NOTE: A 7/8" wrench is required for '96 models.
10. What about factory torque settings when installing a new muffler system?
All factory torque specifications are noted in the CORSA
installation instructions included with each CORSA C4 muffler system.
11. How are the systems packaged and shipped?
Each CORSA muffler is individually placed in a protective plastic bag and the
tips are double wrapped. Each muffler is then carefully packaged along with custom die-cut inserts and inner packs into one master carton to protect each muffler and tip. The center muffler, under-the-axle pipes and
hardware are packaged in a separate carton to prevent possible damage to the muffler cases.
Each master carton is constructed of double-wall, high impact resistant corrugated cartons that ensure that every hand-built CORSA
muffler system will arrive in perfect condition. All orders are shipped by UPS Ground unless otherwise requested.
12. How much does the CORSA Power-Pulse RSC™ C4 system cost?
All pricing can be found on our Ordering Page.
13. Does CORSA offer a warranty?
CORSA's
Power-Pulse RSC™ exhaust systems are handcrafted in the U.S.A. and backed by a Limited Lifetime Warranty and are "Guaranteed for as long as you own your C4."
