the exhaust is clogged up and how can i clean it with or will i have to replace it?

 

if its your cat your talking about, you can beat the guts out of it, or just buy a replacement.

 

well what do you mean its clogged?? and how do you know if it even is clogged? because if your refering to your cat..then you can do what I did and just go to town on scraping out the insides of it and bashing all of the crud/chared insides away .. I did mine with a crow bar.. the weapon it totally up to you
