Question about 2001 GMC Denali
While driving into work this morning while at highway speeds, The engine on My 2001 Denali became loud all of the sudden. The gas pedal felt like it had more pressure(pushback) than usual and the truck began to vibrate noticably. It almost sounded like there was a hole in my exhaust but the engine was much louder than normal (I have an aftermarket flowmaster muffler). I also noticed a bit of power loss and lack of repsonsiveness. Im clueless as to what this can be. Please help!
