Iwas wondering what you call that gas cover that the bullets have and where I can get one. Also has anyone heard of g-force exhust systems and if they rreally are better than the flowmasters, the whole cat-back with x-pipes =$480 w/install and to just replace the mufflers is $240, I have the stock H pipes on my 2002 gt. Also I want to get the pulleys, but I live in the desert, and heard that it might cause my car to run hot or mabye even over heat. Also I want to get 4;10's but use my car for all tpyes of driving, am I better off with 3;73? look forward to your advice thanks
