mines the same way.need a pipe like ddm.the fire hamer has smaller tires is the reason for more punch off the line
I found with my FH with those smaller tires and gearing with a pipe that it has a ton more punch off the line than stock muffler on and the car gets to top speed very quickly. Bigger tires and a larger pinion gear on the motor will help with a little slower take off but more top end. I'm surely not wanting any gearing than the stock 19/48. I'm thinking I would like a 21 to 22 tooth pinion gear on my car.
