Our Verdict
The CORSA Sport Cat-Back is our top pick for the 2003–2010 Dodge Viper SRT-10 8.3L V10.
CORSA’s patented Reflective Sound Cancellation (RSC) delivers a savage wide-open-throttle bark with zero cruising drone — the best all-around cat-back for a street-driven Viper. On a budget, the Borla S-Type is the loudest race-bred option (around $1,185); the MagnaFlow (around $1,453) is the deepest, most refined tone.
Shop Our Top Pick →A Dodge Viper SRT-10 cat-back exhaust is the single most rewarding upgrade you can bolt to America’s naturally aspirated V10 supercar. The 2003–2010 Viper SRT-10 left the factory with an 8.3L (505 cu in) V10 making 500–510 hp — and the 2008–2010 ZB II grew to an 8.4L rated at 600 hp / 560 lb-ft. All of it deserves better than the restrictive, heavy stock exhaust. At NLP Performance in Tampa, FL, the three cat-back systems Viper owners ask about most are the CORSA Sport, the MagnaFlow SYS C/B, and the Borla S-Type. Here is how they stack up on sound, weight, warranty, and price.
Why Upgrade the Viper SRT-10 Cat-Back Exhaust?
A cat-back exhaust on the Viper SRT-10 typically frees up 8–15 hp at the rear wheels and sheds 10–20 lbs versus the factory system, while transforming the V10’s voice from muted to menacing. “Cat-back” means the system replaces everything from the catalytic converters rearward, so it leaves the factory cats in place — keeping your Viper 50-state emissions-legal and preserving the check-engine-free tune. Every system here is built from T-304 stainless steel with mandrel-mandrel bends for maximum flow and lifelong corrosion resistance.
The 8.3L and 8.4L V10 is a low-revving, high-displacement engine that responds best to free-flowing, straight-through mufflers. Because the Viper’s exhaust exits are so visible — and the car is driven for the experience — sound character and drone control matter as much as raw dyno numbers. That is exactly where these three brands separate.

Frequently Asked Questions
Does a cat-back exhaust add horsepower to the Viper SRT-10?
Yes. A cat-back exhaust typically frees up 8–15 hp at the rear wheels on the Viper SRT-10 8.3L/8.4L V10 by reducing backpressure with straight-through, mandrel-bent stainless tubing. The bigger gains are in sound, throttle response, and a 10–20 lb weight reduction versus the heavy factory system.
Is a Viper SRT-10 cat-back exhaust street legal?
Yes. A cat-back exhaust replaces only the components after the catalytic converters, so it leaves the factory cats in place and keeps your Viper 50-state emissions-legal. It does not trigger a check-engine light and requires no tune.
Which Viper SRT-10 exhaust is the loudest?
The Borla S-Type is the loudest cat-back in this comparison thanks to its patented multi-core straight-through design. The CORSA Sport is aggressive at wide-open throttle but stays drone-free at cruise, while the MagnaFlow SYS C/B is the deepest and most refined.
What is CORSA RSC technology?
RSC stands for Reflective Sound Cancellation, CORSA’s patented internal muffler tuning that cancels the specific sound frequencies that cause interior drone. The result is a Viper cat-back that is quiet and comfortable at highway cruise but roars under acceleration.
How long does it take to install a Viper SRT-10 cat-back?
Most owners install a Viper SRT-10 cat-back in about 1–2 hours using basic hand tools. These are direct bolt-on systems that mount to the factory hangers with no cutting or welding, and no ECU tune is required.
How much does a Dodge Viper SRT-10 cat-back exhaust cost?
At NLP Performance, Viper SRT-10 cat-back systems range from about $1,185 for the Borla S-Type to roughly $2,505 for the fully polished CORSA Sport, with the MagnaFlow SYS C/B in the middle at around $1,453. All are T-304 stainless with lifetime or million-mile warranties.
