So ive herd alot about the tuned tc's cloging cats and ive noticed soem power loss... maybe its the fact of me moving to FL and still being on a NY tune but i think my cat might be clogged. Just how bad do u think a gutted cat and muffler delte would sound?

 

Im running catless with no muffler, and as long as im not stepping on it when i pass a cop, they don't even look. But going WOT, will get their attention. Im guessing with 2 cats in series and one punched out, that it will be "tamer" than my set up. AKA go for it!

 

Only way you can clog a cat is by running leaded gasoline

Or by actual debris in your exhaust, and if you have that I'd be more worried than a clogged cat being your problem

 

idk man ive felt a big power drop livivng in a more dusty area and i here alot about tuned tc's clogging them. not reli sure of the resion but i would guess from extra air flowing threw from putting out more boost

 

clogging cat supposely will affect the exhaust flow inside the pipe because its like a big chamber in the pipe. and it suppose to lower the hp in the vehicle. but whats his name that used to have a s/c tune gain like 6-8hp from doing the hollowing cat and resonator delete so idk.
