Looks like my cats are clogged. I need some advice or tips on how you guys gutted the dual cat setup. I cant afford to spend the $275 for a catco dual setup from Summit

if you can unbolt the catback & look directly into the mufflers you can take a crowbar & break up the material inside. Every once in a while crank the car & rev it to blow the chunks out. If you can't do it like this I have no idea.

 

Gutting the dual setup is close to impossible. I have SLP headers with the dual cat setup and I made it so that my stock GM converters are slipfit. I have one set that I gutted and one set that are relatively new. Gutting them AFTER I separated them from the dual cat assembly was easy. But, I can't see how you would be able to gut them while still in the assembly. You would have to chop them out of the assembly with a sawzaw, gut them, and then weld them back in.
