I have done some searching but haven't found anything yet but does anyone out there make an H pipe for a 68 Barracuda with a 360 with correct 340 S exhaust manifolds so basically a 340S?
 
I just did a 74 Duster with xpipe from TTI. He would be best to check out.
 
I guess I should have stated that I wanted to use 2.25" diameter front to back, tips are also 2.25" and prefer an H pipe over an X, TTI offers 2.5" and 3".
 
Make call to TTI and ask for Mike.
He will ask for your manifolds being used casting numbers or what headers you are using.
honestly a 2.25" system compared to a 2.50" system is not much difference.
If you order a system, you will have to go thru like Mancini to purchase but Mike will tell you what system to go with.
 
Why not just make one ?
I have been thinking about making one for my dual 3 1/2' dumped system, but not sure if it would even be worth it`s weight !!

Wow! If your dumping dual 3-1/2” worth the exhaust- will an X or H pipe really matter?
 
Exacto mundo , thinking it would be just adding weight ..

"Exacto mundo" Now that is really dating yourself sir! LOL!
learned that from the ole "Boob tube." Aaaaaaaa! (Thumbs up in a black leather jacket.)
 
My down pipes are , from TTi using (340 hipo) exhaust manifolds run into a pypes stainless 2 1/2 "x" pipe cross over.... studies show that over 3000 rpm they are bypassed any way (and this is where long tube headers really shine in a juiced up motor) little difference between "H" and "X" crossovers other than fitment and sound pulse cancellation

If your running the exhaust to the rear with tips 3" is going to tough to fit between the rear rails and the gas tank on a barracuda
 
3 1/2" collectors?
yeah, home made 3 1/2" mufflers/3 1/2 turn downs in front of rear axle, not much back pressure , lol
Thinking a crossover of any type would just b adding weight , x pipe would probly change the sound some , maybe for the better, but I doubt it would help any. .
This thing doesn`t run like it should , so far, to me anyway , still tuning and refining it.

It needs some backpressure! LOL

Should have a little, 12" bullet mufflers w/ 3 1/2' spirals welded about half way up in them , more 3 1/2" pipe then the turn downs .
Think it needs more ??
I have thot about this , haven`t come to any conclusion-still leaning down my throttle body system occasionally.
 
I really missed the off-idle torque, when I cut mine out to fit the GVod. I mean, it was a shocker!,lol.
My car is a 68 Barracuda with a manual trans and I am running a 230/237/110 cam at 10.95 Scr ~180psi cylinder pressure, and the TTIs.
So after a lotta tuning work,and not getting it back;my cure was to just install the Commando trans gearset with the 3.09 low. That gear is a 16% improvement. I'm not saying that the H was worth 16%. Just saying the 16% more starter-gear did the trick. Now my 3.55s take off like 4.12s...... in first gear anyway.With a clutch car and 3.55s I spend a lot of time below 2800, which is 20mph in first/33 in second/45 in third/ and 63 in fourth, and in OD, 65=2040 rpm. So I missed the torque all the time, when just put-putting around. I like the 2800 shift for the happy sound the engine is making, and it's just starting to wake up.
If you are running an auto and more than about a 2800stall, I kindof think the crossover would be a waste, for anything but cruising.
I have dual 3s front to back. No problem snaking it to the bumper.With 3.5s tho, it might need a lil pinch as it goes by the LH rear spring hanger. Otherwise the 3s have plenty of room. Even at lowered ride height.
The H-crossover was not 3". I didn't measure it. It mightabin 2.25 or perhaps 2.5.
