Exhaust upgrade for 1988 Tbird Sport ?

yep, install the headers and H-Pipe, and then modify the rest to fit.

If you have a column shifter, you may need to adjust the column linkage a bit for the headers to fit. A non issue. Bolting them on is easy stuff. get new bolts. The exhaust manifold bolts are different lengths. I had grade 8 bolts and lock washers and never had an issue. Or, run down to any parts store and get some header bolts. Smaller head and easier to access with a small socket.

$60 is a great deal. When I had my stock H-Pipe many moons ago, I broke all of the catalytic stuff out and then bolted it on. The stock Mustang parts are way better than the stock stuff you have now, and from all I have read, is good for about 275 to 300 horsepower.

One thing I would like to add to all of this. If you do not require the shiny 87-93 Mustang LX stainless steel tail pipes then get a set of the 87-93 Mustang GT tail pipes. Here is the reasoning behind this, the LX tail pipes will hang down below the body of the car and to lengthen them requires additional stainless steel tubing, a tig welder, grinding, and lots of polishing if you want them to be the same diameter. If you are not worried about the same diameter then you will be adding about 8" of "tip" to the end of the tail pipes similiar to echo chambers. The GT tail pipes have a slight turn down on the end of them and they will tuck up high so you will not see them. It is very easy to just have an exhaust shop lengthen them and no one will be the wiser as they are almost hidden from view. I did this on my 85 Turbo Coupe with a single 2.5" exhaust on the car so I used the driver side GT tail pipe and had it lengthened. Buddy of mine owns an exhaust shop so he was always willing to try new stuff and had a shiznit ton of Fox Mustang stock exhaust parts piled up to experiment on.

One other clarification would be that the "mid pipe" that is referenced so many times is the short piece of exhaust tubing between the rear s on the H or X pipe assembly and the inlet of the lers. Again, this piece is very easy to lengthen and with our cars has to be to located the lers correctly. The T-Birds are longer in the mid section and rear end than a Fox Mustang.
