Both are off of my '03 GT and obo.
The BBK is the short O/R X pipe for their LT headers.
$100 plus shipping.
The stock mid-pipe is just as it says. It may have 15k miles on it, Ford replaced my original one after it got a broken weld. I'm pretty sure this will bolt to any 99-04. Not sure...
I have a magnaflow offroad xpipe for sale. Ive only had it for 200 miles. Its practically brand new. Its still on the car at the moment. Need to get a picture. Here are the specs.
Also have a set of o2 extensions...
