Heard a BANG!

I was making my way home from school today doing 60mph and all of a sudden heard a BANG! I pulled over at a nearby lot and got under the truck and all. When it happened I though I backfired or hit a balloon. Nope. Just blew a muffler, 1 down 1 to go! I pulled up home and my dad was outside and asked why the truck sounded louder,, so that confirmed it. I've been wanting to get straight pipes anyway!

Re: Heard a BANG!

Yeah it must have backfired to blow up the muffler.
Could it be running rich?

No, it only throws black smoke when I floor it up a hill. I have a feeling it blew the muffle because I have a heavy foot, so there was always a little more air trying to go through them then intended by GM.

Next thing on my list is go to the muffler shop and get straight pipe to replace the mufflers.

Re: Heard a BANG!

Yeah I had one blow on me one time after I washed the engine and underside real good. Scared me to death, because I had my foot in it when leaving the car wash. Then all of a sudden BOOM!

Re: Heard a BANG!

Mufflers only blow up when they have fuel in them and it gets ignited. You're running rich!!!

It's a diesel. No way it could have done that.
