3" Dynomax Ultraflow Carnage
well I'm pushing about 950 HP so I'm guessing it was too much for the muffler. Who am I kiddin'....actually I'm embarrassed to say the distributor was 180 out. Nothing like starting a car in a small garage and having a unexpected explosion so powerful go off that blows posters off the wall and shoots a giant mushroom cloud out the front of the garage. I think my neighbors thought they had finally got rid of me :lol:
