Invidia Gemini Stainless Steel Tip Cat-Back Exhaust System will provide your vehicle with a pronounced exhaust note throughout the entire RPM band, and the design improves performance from the increased piping diameter, to the smooth bends that reduce exhaust flow under acceleration. This means that you will have improvements in throttle response, and you will have increases in both horsepower and torque. 

This is a great exhaust system for those of you who enjoy the occasional weekend track day, or who enjoy the spirited drive. With the stainless steel tip finish, this exhaust system will look great on the exterior of your vehicle. This exhaust system comes with a 3" piping diameter and 4" muffler tips.

Exhaust hangers are welded onto the OEM locations of this exhaust system so you don't have to worry about making further modifications to the body. New hardware and gaskets will be included with this exhaust system to make it ready for installation.
