I'm thinking about gutting out the two small (pup) cats, but leaving the main ones alone. Anyone done this? Was it worthwhile in terms of horsepower? What did it sound like afterwards?

 

I'm guessing it is going to be louder!

also, how do you plan on doing that without any of the "chunks" going into your regular cat?

BTW:

when you start fouling out O2 sensors I have 4 (all 4 of them) that i'll sell you, they have about 5000 miles on them.

 

Well, I'm guessing it will be louder also, LOL. I was planning to use a screwdriver and a hammer to break up the guts, and shake/pour the chunks out the front.
