yesh, full pipes coming out of the rear would be dope too. It all sounds good quite frankly

My tail pipes are also mandrel bent 2 1/2 inch pipes (the whole exhaust is 2 1/2) with Flowmaster lers. I got my Bosch O2 sensors from Ebay super cheap.

If you order an H-Pipe, it will come with the hardware. I'm a full exhaust kind of guy. Dumps sound great, but the drone and excessive noise under the car makes a long drive a little uncomfortable, but, that is the decision of the owner. As far as the O2 harness, I extended mine a few inches, but the extenders are a simple and good idea. I lengthened mine before I knew they existed years ago.

For a visual reference 2.5" Dynomax Mustang LX tail pipes will fit fine. A little length needs to be added to make them reach the bumper but that's it.

great looking car; thanks for the pic.

Where did you find adding extension pipe was the easiest?

At the end of the tail pipes. Just make sure you order a set with regular aluminized pipe instead of stainless tails.

For the love of GOD dude please don't get Flowmasters and run dumps. Trust me on this. The resonation will drive you insane.
Now...with stock gearing, maybe not so bad. And if you had cats, it might even be reasonable.

But say goodbye to hearing any bass at all out of your stereo, and if you have a headache and have to drive it, that headache will worsen LOL.

Borla ProXS will be reasonable, and will sound great to those around you (have confirmed this myself).
Mac's square-shaped welded chambered lers (they look like a "square Flowmaster" you might say) also roar very well without a stupid amount of drone. I may try these as well.

A friend's '89 Mustang hatch has 4.10 gears, a full GT40 setup, BBK shorties, and I think just an off-road H-pipe. It MIGHT be a MAC ProChamber. But the lers are those Mac chambered ones. (The ProChamber deepens the sound and does le it just a little. I can confirm that from experience as well on a third unrelated car). But this Mustang, from the outside, is just a guttural roar with very little metallic ringing or hum/drone. Especially between 2500 and 3000 RPM. I'm really surprised at how tolerable it all is. There is obviously no comparing a 'Stang and TBird/Cat in the road/wind/exhaust noise inside department. It's not anything groundbreaking, but it's BETTER than my red cougar was with catless, Flowmasters and dumps.

I don't know what happened last year. I just snapped and couldn't deal with the drone anymore. When I was 18 (9 years ago) I thought the setup was awesome. I also had a 220-horse, 2.73 gear, 16 second 1/4 mile car that was a pro-street big block in my head. Context is important LOL

I will stay away from the dumps.  I can see how they may produce more noise then "character"

Don't spend on extensions, just buy new sensors for something that came with an HO, like a Mark VII or a Mustang.  They'll be the correct length already. 

Just say no to dumps; people only get them as a cop out from running a tail that they have to work for, to save money or time.  If you don't have cats its worse, just because of all the CO pooling under the car at stops.  There's a reason that the law says your exhaust has to exit at the perimeter of the vehicle, and unlike so many other laws, this one is for safety.

Another question: whats the deal with the cheaper non-chrome headers; the ones that are just painted. They get a lot hotter then chromed ones? Should I stay away from those in the future..?
