i have a '99 mustang gt with stock headers. i'm looking to replace my 4 catted stock h pipe with either a catless x pipe or a catted high flow x pipe. what would you recommend i use with stock headers? does it have to be just a long x pipe?

Any brand x pipe will work. Get what is in your budget. As long as it's specified for your year and isn't advertised asa "shorty" it should fit.

I bought the pypes one and the fit was 100% perfect. I chose the offroad version with no cats but since have switched to a offroad H. Pm me if your interested in my offroad x. It was only on the car for 5,000 miles and is in perfect shape.

whered you buy it? Any other parts needed to install or everything included? do the factory O2 sensors hook right up to it or what?

i bought it from rpmoutlet.com because they had the best price around by far. O2s bolted right up. the one thing is that i had to reuse the old studs from the stock H where the cat-back mates, but a with a little wd-40 they came right out.
