I have a 94 gt, already with a Flowmaster Cat-back, and I was looking into headers. I am going to put on some sort of x-pipe(stocks cats suck), and was thinking about either long tube or equal length-shortie BBK headers. Which, if any would be a better buy or performance gain for my mostly stock set-up? My set-up right now is stock, possibly a BBK cold-air and maybe a 65mm Throttle Body appearing soon, but nothing else. Thanks for any input/advice guys.
