You'll have a hell of a time with long tubes.  And I thought I told you this before, fit the headers, fit the H or X, hang the tails (which as I read recently will be proper length from Stinger), mount the Mustang mid-pipes, slip the lers onto the tails, prop them up in place with a jack stand or something and measure the gap.  from the end of the mid-pipes to the inlet of the lers will be in the neighborhood of 4 inches, then you'll have to add so you've got enough to get into the ler 1 1/2 to 2 inches and over the mid pipes the same.  So ballpark around 7 or 8 inches of pipe per side.  That pipe will need to be bumped up to 2.5" inner diameter on the end that slips over the mid-pipes.

Long tubes can be a PITA to install. Shorties can be installed under the hood easily. Mid pipes are the pipes that fit between the lers and the h-Pipe. You will need to fit everything. As I stated before, just install the headers and H-pipe yourself,  have the tail pipes ready for them, shops around here don't have them, they have to order them, then take the car to your local ler shop and let them do what they need to do. Just by going by somebody elses measurements may mess it up for you, and, on my car, the mid pipes are slightly bent to fit the car and to meet up with the ler in the proper location. Be patient and do it right. If money is an issue, then save it til you can do it right. Your mechanic should have a lift. let them do their job and that way you don't have pipes hanging too low, not fitting, and a mess of tubes under the car.

The mechanic I go to did a great job with my current exhaust....very neat and clean work. It's just not what im looking for but all I could afford to do at the time without running obnoxious open manifolds around town. It's just the stock manifolds/ypipe/extensions/lers(dumped at axle).

Would a pair of flow tubes between the h and lers work, or would I still need more length  ?  http://www.mustangsunlimited.com/itemdy00.asp?T1=43800SS+01
