when my cat blew, it gave a constant power loss above 2k rpm, below that it would drive sluggish, but the car could still accelerate.... till 2k rpm
when your cat blows, it will veeeeeery rarely blow the entire comb out, mine blew about 1/5th out and it shattered, and those shattered pieces would clog up the rest of the comb.
when turned off, those pieces fell into the matrix so the comb was not clogged no more. but after turning it on, it only took about 10 seconds tho till it was clogged again.... so i guess those 10 mins are a bit long.
oh yeah, +1 about asking those extra questions, haha i was just in debate mode sorry
