About CORSA Performance RSC Technology

CORSA Performance's patented Reflective Sound Cancellation (RSC) Technology is the engineering breakthrough behind every CORSA exhaust. Unlike conventional mufflers that restrict flow to control sound, RSC uses precision-tuned internal chambers to cancel drone frequencies before they exit the tailpipe. The result is a system that flows freely for maximum power while eliminating the cabin resonance that makes long drives uncomfortable. The 14466BLK uses this same technology to give your Grand Cherokee SRT a sound that turns heads at a stoplight and stays refined on the highway.

Frequently Asked Questions

Does the CORSA 14466BLK fit the 2012-2013 Jeep Grand Cherokee SRT8?
Yes. The 14466BLK fits every year of the WK2 Grand Cherokee with the 6.4L HEMI, including the 2012 and 2013 SRT8 models. Note that 2012-2013 SRT8 fitments require installation of the restrictor pill assembly included in the hardware kit.

What is the difference between the 14466BLK and the 14466 (polished)?
Both are Sport sound level cat-back systems for the same 6.4L Grand Cherokee SRT. The 14466BLK features Black PVD coated Pro-Series tips. The standard 14466 comes with polished stainless steel tips. Performance is identical between both versions.

What is the difference between the CORSA 14466BLK and the 21058BLK?
Both fit the 2012-2021 Grand Cherokee SRT 6.4L V8. The 14466BLK is tuned to the Sport sound level, which is deep and aggressive without being overwhelming. The 21058BLK is the Xtreme sound level and is notably louder. CORSA does not recommend pairing the Xtreme system with aftermarket headers.

Will the CORSA 14466BLK work on a Jeep Grand Cherokee Trackhawk?
No. The Trackhawk uses a supercharged 6.2L Hellcat V8 and requires a different exhaust system. The 14466BLK is designed for the naturally aspirated 6.4L HEMI found in the SRT and SRT8 trim levels only.

Does the CORSA 14466BLK require any cutting or welding?
No. The 14466BLK is a complete bolt-on cat-back system that connects to the factory catalytic converter outlets using included Torca clamps. No cutting, welding, or fabrication is required.

Will this exhaust trigger a check engine light?
It may. High-flow cat-back systems can reduce back pressure enough to trigger a P0420 or similar code on some vehicles. This is a known characteristic of the design and does not indicate engine damage. CORSA includes this notice in their product documentation.

What warranty does the CORSA 14466BLK carry?
CORSA backs the 14466BLK with a limited lifetime warranty against defects in materials and workmanship. Under the Magnuson-Moss Warranty Act, installing this exhaust system cannot void your vehicle's factory warranty unless the manufacturer can prove the part caused a specific failure.

How much horsepower does the CORSA 14466BLK add to the Grand Cherokee SRT?
CORSA rates the Sport cat-back system at up to 26 horsepower and 40 lb-ft of torque gains over the factory exhaust. Actual results vary depending on vehicle condition, altitude, and temperature.

Is the 14466BLK street legal in all 50 states?
The 14466BLK is a cat-back system that retains the factory catalytic converters, making it 50-state street legal in terms of emissions equipment. California residents should note the Prop 65 warning below.

How long does installation take on a Jeep Grand Cherokee SRT?
Most installations are completed in 1 to 2 hours with basic hand tools. CORSA includes detailed printed installation instructions with every kit.

Can I hear a sound clip of the CORSA 14466BLK before buying?
Yes. CORSA Performance posts official dyno and drive sound clips on their YouTube channel and website at corsaperformance.com. Search for 14466BLK or the Grand Cherokee SRT Sport exhaust to hear the Sport sound level before purchasing.
