MAC headers
 

I purchased a set of mac headers but i gotta dual cat setup...
Where can i put my cat come emissions time?
would i put my cutout right after the y-pipe and then just bolt up my cat when i need it back it?
or is that to close?
anyone got pics from underneight a car to see how this will look?

ALSO, i can put in an S-pipe and if anyone has a pic of that, that would be cool

Where you have that big buldge under your passenger side floor. But don't sweat it, I mean just get it put on however for air care and then remove it.
