99Stang_V6

from what ive heard, people have been saying that mac shorty headers for the v6 are worthless....my friend has those on his v6 and they look helluva lot better than the stock ones...how ppl be saying that they dont do squat...he even noticed a difference in acceleration...i already have an o/r x-pipe for my car and really wouldnt trade it in for longtubes and shorty h-pipe...i mean i dont see what is so worthless about v6 mac shorty headers....someone help me out..

all add-on will help that v-6....be too say you can actually feel a diffence just from a header change is an overstatment..you see about 5-8 hp with just headers at best... it takes about 25-30 to feel any seat of the pants hp feel

L/T's will give slightly larger gains performance-wise, FYI...
