Muffler underbody clean up
 

So i noticed the under body is a mess Aerodynamics wise


well in the back end it has the 2nd muffler so under it is pretty "dirty"


is there anyway ti fix this it all ready has a factory 6" air dam :eek: that i will be replacing soon due to "minor damage" (i just want it to look pretty :) )

resonator drag
 

Paneling over the resonator wouldn't do any good without a complete belly pan upstream.So you're kinda stuck.

Where there is the will, there is a way.

The bellypan and airdam sorta fix the same problem. Are you going to shorten the airdam? The bellypan is more effective. Lengthen the airdam and the bellypan is less effective. It's probably an non-linear relationship and too case specific for a general rule.
