exhaust problems
 
just got back from a lil road trip and my exhaust makes a weird humming noise at 60-70 mph 2000rpm..only way i can explain it,is that its sounds like a loud bass noise..:confused:anyone have any idea what it may be...

Is the exhaust not touching any part of the body somewhere? Does it look like the sound is coming from the end of the exhaust pipe, or more from the engine bay?

well engine rpms increase and engine gets louder with higher speeds (obvious) but the significant increase in noise might mean a crack or hole in the exhaust

take a close look at the underside of the entire exhaust, but more specifically where it attaches to muffler as the underside there is prone to rocks shot up from your back tire

you might have a hole or crack somewhere and don't notice the noise until you are revving at higher rpm. also, best to check in morning on a cold day and see if you see any exhaust fumes leaking out of anywhere beside the muffler tip :)

check for a crack right on the bottom of the muffler, happened on mine with only 32k miles
