Plugged Muffler??

Who alls heard of a plugged muffler that restricts bad enough the engine is down on power? I work for Halliburton and had to hotshot frac trucks back to town yesterday. On the second trip I jumped in a new truck, its actually an 06 but its been sitting in the shop getting a shower put in it (its a straight truck-no trailer) with 677 hours on it and 3500-somethin miles. So its still basically brand new. Its got a twin turbo CAT C10 in it.

So I start going and notice it has real bad response, pedals to the floor and it barely accelerates. Anyway I get on the interstate and it goes 25mph TOPS. Pull over, the frac mechanic pulls up, we can hear hissing coming from the top turbo, he says "Ill bet its a plugged muffler." Im standin there like "dude, your crazy. Gonna take the muffler off on the side of the road for nothing."

We get it off, and to my surprise it fixed it. The soot that fell out from inside the muffler literally looked like little chunks of coal. But I was smilin the whole way into town drivin it straight piped!! And the jake was LOUD!! My suggestion for straight-piping all the company trucks didnt go over so well though. Bummer. Whos ever heard of that before?

Its funny you say that, on my 05 F350 both the cat and muffler plugged up only after 5000 miles and had to take both off in place of strait pipe! Funny how that happened! (I know your serious but I had to be )
