I have a Loudmouth 1 on my TA and it pops in the morning when i leave the house everytime i let off the gas to change gears. It only does this for about the first 1/2 mile to a mile though then it stopes for the rest of the day. My exhaust didnt pop before the loudmouth was put on. Anyone elses pop? Should it do this?

I have a Flowmaster catback and before I put L/T's and ory pipe it done that for about the first half mile or so. It is normal, but I don't know why. Don't be alarmed.

I think it's because the air pump is on when you first start it up-causing a slight backfire.With the stock exhaust my car does pop from time to time.

Pull the fuse on the air pump and see if it still does it. I did away with the air pump and egr. In the engine compartment there is a fuse just for the air pump. Pull and see if it still does it. THat way you will know that is what's causing it.
