First time mustang owner. If this question has been asked please point me in the right direction. I've got a 97 gt with long tubes that are trashed. From there it goes into an h pipe to flows dumped in front of the axle. No cats. I'm putting stock headers back on the car. What do I need to connect the stock headers to the rest of the current exhaust setup?

 

You will need a full (normal) length mid-pipe. The one you have now is shorter to compensate for the extended length of the long tubes.
