not usually a muffler unless it basically rusts out. a cat would be more likely

if you have the stock muffler you have a major exhaust restriction! straight pipe it.

I was actually wondering this same sort of thing. I have an early '99 with a cat and have noticed higher and higher EGT's over the past couple of months. It's not running as well as it had in the past, either.

I am leaking some boost around the intercooler up pipes to, which I'm sure is contributing to the higher EGT's.

Anyway, just thought I'd comment. I plan on cutting the cat and muffler off of mine anyway in the very near future. Hopefully that improves things for me.

I live in Kansas, and the guy I bought the truck from lives in Kansas, and I'm pretty sure the original owner is in Kansas (but I could be wrong on that one).

I'm not sure where the truck was born though.
