I don't know what is wrong with my truck but I've been hearing this weird noise. It sounds like it is coming from the exhaust. It sound like a deep sounded whoosh or something like that. It's just kind of weird. Does anybody know what is happening with it. I only have a filter on my truck. Any help appreciated

 

Uhhh, okay, when , where , why, how etc. need more detail before a guess can be attempted,,, Sorry..

 

Check your muffler hanger. Mine came unbolted and made all kinds of noises that were wierd. Hope this helps.

Everytime i floor it it makes that sound. It happens right before it shifts into 2nd.

 

it sounds like your boost bypass needs adjustment, or you have a loose vacuum line that allows the egr to open prematurely....just a guess.

If the sound comes from the rear area, possibly a loose muffler clamp or a cracked exhaust/ muffler.. another guess

 

Do you have a plug hanging out of the head by a thread? might wanna check it out , Sounds kinda like what my trucks did when the plugs came loose

 

Actually if what you are referring to is sort of a "farting" noise, most L's will do that stock. It's because the shifting pattern of the transmission some cylinders are just pumping air. Mine did it once or twice shifting at full throttle. It sounds funny but it's normal.
