on the factory exaust for the mojave , do you cut out the plates around the spark aresstor? or does anyone know the way to do this?

 

i didn't know that the stock exhaust had plates...are you just trying to let it breath better

 

the exahust goes in the big tube u see (outside casing) , then in side it there are four tubes it has to pass through, then it has to pass through four more tubes before it can pass through the spark aresstor and exit outside for u to see if its running rich or not
