Hey everyone,

I don't actually know if this is really happening, so I figured I'd see if
anyone has heard of it before. My exhaust pipes have rusted to hell. One of
my headers is broken all the way through, and I have a rust hole in the
manifold. That being said, my van is loud. The engine runs strong, and
sounds great(other than the loud part). Idling is also normal and steady.
Sometimes, though, when I'm coasting down a hill, it almost sounds like I'm
misfiring. I can't tell if it's just my crappy exhaust that's clinking
around and making it sound like that or what. It didn't make sense that it
would misfire when coasting, but not at idle. Is this probably just my
exhaust playing tricks on me, or have you seen this happen before?

Also, I've heard that a leaky exhaust can burn a valve. Is that true? And if
so, what is the best way to check the valves? I've been putting off the
exhaust replacement because it's so expensive, and I'll have to replace
pretty much everything, but I guess I'll have to bite the bullet soon. I
emailed tencentlife from the Samba about his stainless steel pipes, but
haven't heard back.

Thanks for the help!
