It makes a difference on any car . . . the amount gained will vary but because it increases efficiency its beneficial to all.

You have a point, it's just a stock 5.0 Crown Vic that will probably hardly ever have the pedal pushed all the way down. In your case I don't think the price difference in the X pipe would justify the gain you would see. Go with the H.

put a white paint stripe on the pipes and run it under load... where its most burnt is where you burn the crossover in.
Chasis Dyno and a mirror works nice ;)

OK I am new to the hotrodding thing obviously, but can you guys explain what the H-Pipe and X-Pipe are for me so I have a better understanding of it. If it is pretty beneficial to have one on a truck that is pushing a decent amount of HP/TQ then I will have to take the 74' Truck of mine and have one put on it.

Yes, The X pipe will make a noticable difference in sound and power on even a stock motor. However, there are different types of X pipes. Some that work and some that don't. ie; the $30 X pipe mentioned above will require a good bit of custom bending to get it to fit your car. This custom bending will most probably NOT be mandrel bent locally. Custom bending is expensive and also restrictive if not mandrel bent. Therefore the $30 initial investment will increase and may not give you the intended affect. There are Mandrel bent universal X pipe kits that run from the manifolds/headers all the way to the mufflers. I would investigate these.

Any time you goto an X pipe your gonna free up some backpressure. Wich is good for the high-end. You'll gain some HP, but you'll loose some torque.
Unless you already have a high flowing motor with a very restrictive exaust.
This same rule applies to an H pipe but not as much so. Or with going to mufflers that are too high flowing. Unless once again you got a high flowing motor.
Example is I have a set of Dynomax headers, 2x dynomax super turbo muffles, and a H pipe. Wich was great for my old engine setup, but with a new set of good flowing heads, a victor jr intake, K&N air filter, and a 750 holley, now that exaust is too restrictive, time for a set of flowe master 40 series 2 chambers.

- Also note the X or H pipe needs to be installed as close to the headers as possible, wich basicly means behind the transmission because who wants to drop thier exauhst just to do some transmission work.

I have a 1990 CV. Came stock with duals and H-pipe. Seems to me they wouldn't put an H-pipe there if it wasn't useful. I know the dual does more HP than the single.
Does any one know of a cat-back for the CV (302) that has an X-pipe? I see them for the mustang, but dont want to buy one and find out it won't fit the CV.
Magnaflow makes a muffler with an X-pipe inside (2 in, 2 out). Maybe I should try that. Has anyone put one on a CV w/ 302?

Coffee boy while your information is appreciated, I think it would be better suited to keep to current posts. The creator of this thread hasn't posted here in over 2 months as this thread is over 2 months old now.

We get a lot of 1 time posters that dont show up much after their first time. Generally if its buried in the past there is a reason for it .

BTW welcome to the boards
