Checking Timing??

If this is a street car (& it sounds like it is) I would suggest putting tailpipes on your car. Your taking away some low end torque having it come straight out of your mufflers. Personally I don't like the sound of straight out of the muffler. A real cop magnet. Loud is not always better. Just my opinion though.
