To me the x pipe smooths out the pulses from the exhaust, More euro sounding. I prefer the lower frequency pulses from the true dual exhaust. I understand the science behind X and H pipes but am willing to take the penalty for better sound IMO from true dual exhaust. even better, side pipes.
I bought a true dual exhaust because the manufacturer wouldn't make an X or H pipe with it. I'd like to put an H pipe in it when I put them on the car but I'd still like to be able to remove the exhaust system if necessary later as well - I'm not sure that can be done.

I can remove my H-pipe in one minute (probably less if it was a contest).
There are also several different ways to fabricate an H-pipe, Some are permanent, others are removable. (Some are efficient, and others are not.). Lotsa choices.
^^^One side can slide right over the other, clamp if you like. The H doesnt have to be the same dia as the duals.
Stopped welding my systems together yrs ago, they get beads up to the Cross over if there is one, the rest is clamped.

Would you be so kind as to PM (or post) me your suggestion?

Nothing exotic here. Just a couple exhaust tube nipples welded to the collector reducers, a crossover pipe that slides over the left reducer nipple, and then a band clamp to connect the crossover tube to the right side collector reducer. About a pound and a half of material, located near the collector for higher efficiency. Made a noticeable reduction in bodywork drone and exhaust harshness, and these crossovers generally offer up a few free horsepower to boot.
Some guys put flanges and bolts on each side for connection and removal ability. Those work well too. My goal was to minimize the weight of the H connection.
Bought the "True Duals" kit for my 1980 and added an H-pipe where the 2 pipes come close together so its only a few inches long. No problem dropping the whole exhaust if needed. Just remove the mid hangar and unbolt the cast iron manifolds at the donuts. Pull forward and it all drops out in one piece.
It still drones JUST a bit at 1600 rpms or so (40 mph in 3rd) with the windows up...but not annoying at all. Cruising down the highway at 70 mph (3000) its quiet as a Nursery inside.
They did a nice job. I bought a complete exhaust system with no H or X pipe. I should have just bought the mufflers and an X pipe and did what you did. Probably would have been cheaper as well as better.

Thank you... Usually not cheaper though... but yes, better....
My exhaust system is completely welded. You just remove three header collector bolts from each side and two hanger nuts from each side and drag it out the back. I just lean it against a wall or outside fence

Ok, I'm sold that the sound is good and my 496 won't sound like a six cylinder Mustang.
Where in the power band will adding an X pipe increase power?
Bottom end, mid range, top end or all through the power band?
Although X- and H-pipes perform extremely well for a minimal investment in time and money, both offer unique properties that make one more suitable than the other depending on the application. “The two biggest differences between an X- and an H-pipe are sound and power. Generally, the X-pipe will deliver a more high-pitched exhaust note, making a car sound more exotic, whereas an H-pipe gives a dee..................................... ..
