I am pretty well mechanically inclined. I have a good tool invintory. I want to put headers on my automatic 2002 gt. If I get a welder by june I will put on long tubes, X-pipe and reweld my glass packs back on. But if i get to impatient i will put on shorties, and bolt on to the stock H-pipe. The instructions I have read do not seem to be to hard. Any imput from personal experince? Is ther any speciffic headers i need to stay away from? thanks for the help.
