what is the best way to clean the cats in a mufflers with you using heat

[backhoelover]

has any tech or workers found a good way to clean the cats in the muffler with out using heat. i have already tried heat but it is not working. the muffler is not completely stop up just enough for it to drop the engine rpm about 2,000 . also has anyone used the stihl decam yet if so how does it work

Who let the cat out? Who? Who?

Seriously, if you are an actual tech for a dealership, you can't really do that. Got a pic of the cat in question? If it is like Husky's cats, it is multi layer and nigh impossible to clean mechanically. Maybe some kind of acid?

Shooters choice shotgun choke cleaner loosens carbon in the cat better than most other solvents/sprays that i have used.

Heat works, pliers, drills, and cutters work the best.
