We did our own independent test to see what performance gains could be made. At the low end of the spectrum, you can expect a .35 seconds shaved from your 1/4 mile time just from the higher flow exhaust system!!!! Make the next step in your performance upgrades a cat back exhaust. 

Add a Magnaflow High Flow Catalytic Converter for even more gain. These cats even come with an O2 sensor bung installed. Adding this high flow cat does increase the flow of your exhaust, also making it grumble with an even deeper tone. NOTE: This Magnaflow Catalytic Converter is NOT 50 State Compliant.
