Aftermarket exhaust and aerodynamics

I'm interested in getting the nameless axleback exhaust, but I have a question about the effects it will have on the aerodynamics the car. The stock muffler was designed to decrease lift in the rear of the car. Will replacing this muffler cause the bumper to act as a mini parachute, increasing the coefficient of drag, or worsening the handling characteristics of the car.

if you dont have another suitcase style muffler yes it will disrupt your aero. you wont notice it with normal driving but should become more pronounced as speed increases. you could make a diffuser plate to cover the gap though

Would you notice it in a wind tunnel test? Probably. Would you be able to tell a difference in the real world? Probably not.

A Guy Made A Custom Diffuser..I'm Not Sure If It Helps Aerodynamics, But It Looks Like It.
