So I went to fire up the GTP yesterday and it wouldn't start, I turned the key 3 separate times and at the end of the third try there was a very loud backfire/explosion. I was dazed at this point it was like a scene from archer where he's saying mawp with ears ringing. I left it alone for the night because it was too dark and I was to dazed to want to mess with it. Today when I got around to checking it out I found nothing out of the ordinary under the hood so I turned the key to the on position, I heard the fuel system pressurize and I tapped the key to start and it fired right up. well at this time I instantly could tell the car was louder, I looked under the back at the muffler and this is what I saw
so I'm kind of at a loss as to what caused this. the back fire was so big it also cracked and broke both taillights.
