No Drone - This is what sets us apart from other exhaust manufacturers: RSCâ„¢ 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 RSCâ„¢ 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!
