Well, usually when a proper running vehicle backfires through the exhaust its caused by an excess in fuel building up in the pipe and igniting. Some newer diesle trucks will spray fuel into the exhaust to clean the emissions and reduce smoke coming out of the tail pipe. You could have a bent or sticking valve that is allowing extra fuel out into the exhaust, or when it went to clean the exhaust (If your model does that) the exhaust might not have been hot enough to ignite the fuel until you put a load on it causing the exhaust temp to jump igniting all the fuel in the tail pipe.

2004 Dodge Ram Backfiring and blowing Muffler


White smoke....Means a Blown Head gasket.. Now its not bad enough to stop the vehicle from running but its bad enough, to blow out white smoke..now sooner or later it will stop completly, but you dont want to warp the cylinder heads too bad, then you will have to replace them also, so you might want to fix this problem as soon as possible...and the muffler keeps going bad, becasue it is filling up with coolant/ or too much water, which it is not designed to do..You also maybe doing damage to your cat. converters also...so be careful....And Goodluck, and keep me posted...

You probably have a clogged up exhaust system building backpressure on the engine. Check your mufflers and catalytic convertors if you have them something is restricting the exhaust.

Need to check for codes. Need a scanner hooked up and test drive to be able to see what happening. Hopefully someone did not add the wrong fluid because this could contaminate and destroy all rubber parts in the brake system and cause swelling issues.
