What is your goal? There are better investments that will yield better results, check into a tuner (computer tweaking on a dyno). Headders on an engine are after you improve intake / fuel increases. There are optimal tuning gurus that can help you. Just google tuning the 3.8 mustang.

Mark speaks the truth ! ! ! The car has to breath before it can exhale.

I would put an intake and exhaust on first,and a chip.if u swap out the rear end gears its like day and night. I did this to my 2002 v6 and I smoked gts.

Before making any mods I suggest you make sure the heads are in good shape. While he 3.8 is a good motor the heads do have a tendency to warp on certain model years.

What kind of chip should I get? I already have cold air intake and custom exhaust

If you have the intake and exhaust I would switch the rear gears.its a big difference.

It's your rear axle.take it to a performance shop that does mustangs and ask them. It's about$1000-$2000. Price may be different for auto,year,and where you live. Depends on what your looking for speed wise. The other had a good point.if you want a lot might be better to go cobra. I did
