Maverick and Mustang exhaust compatibility

Hi
Does anyone now if the exhaust from a Early model mustang (say 67-73) will fit a Maverick with a V-8/C-4 and long tube headers?
I've managed too put the h-pipe section and a set of mufflers on my car and they came off a 67 mustang. I had too wrestle with them a bit, but did not bend them from their original shape.
I noticed that they don't look quite right. One side hangs lower than it should.
I don't really like having a dump setup and would much rather have a full system that exits out the back. I called an exhaust shop last week and was quoted $800-$1000 for a header back setup. THATS CRAZY!!!! I 've seen people post messages saying they've paid between $350-$700.
He even said he's had experience doing this too Maverick's and he thought it was easy. Easy is $800-$1000!!!!! I would hate too see what hard costs.
I live in Rhode Island if anyone has any suggestions for shops. And If getting a mustang system to fit is feasible I'm looking for feedback.
Thanks for any help you guys and girls can offer.

 

If you check the catalogs, the same long tube header number fits a lot of different Ford/Merc cars. From the header outlet back there is not much the same as far as a factory like fit.
I run the hedmon shortys into a custom X pipe and special muffler connectors and custom bent tails straight out the back. My setup can hardly be seen looking from the side. The muffler connecting pipes are made to tuck up along side the driveshaft. This keeps the mufflers up in the flat open area just ahead of the rear axle.
I designed this system and had it bent at my local Mineke shop that will do this kind of work. The design is for sale to serious buyers but the work and the shipping add to the cost. Just can't do it for nothing. I could make the system back to the mufflers, available for about $500 including the headers and they have already gone up in price. This include the short headers, head pipes, X pipe and connecting tubes all in 2-1/4" size built out of regular alumunize pipe and fittings. Its winter time now and my car is put away. I would have to remove the system to have it reproduced to sell. When I first built this system a couple years ago, no one was interested. This system is designed for a floor shift automatic car. The head pipes leave all the room ever needed to work on the car up near the trans. There are no clearence problems any where. This was was done primarly to get fuel injection oxygen sensors close to the header outlets.
If you use long tubes, they will hang kinda low so the rest of the system will also hang low unless the pipes are done up with an eye to maximum clearence. If the car has power steering, the power cylinder frame mount will have to be replaced with a mount that lowers the cylinder so it clears the header. My design does away with all those problems.
I can supply a paper on the system for you to see if you interested in having it reproduced by a shop that will do custom work.
Good luck.

 

I have long tubes on my '70. I think they are the same part number for an early Mustang. Bought a pair Dynomax 2 1/4" inlet / outlet mufflers that fit up under the rear seat area in front of the axle. A local muffler shop custom bent a full 2 1/4" aluminized exhaust with H pipe and tailpipes for $250. Previous to that I tried to install an early Mustang exhaust kit that came in a box. The tailpipes weren't quite the right angle.

 

I got a quote of $450-$500 to do mine and that was 3in from the collectors (headman long tubes) to custom x anddinomax bulitt mufflers with dumps at the rear .im just going to buy an x pipe from Dr. gas and run straight back to mufflers then dumps.

 

My opinion is that 3" is way overkill on size. I don't think anyone makes a 2-1/4" H or X pipe is why I built my own. 3" is more costly and harder to work with.
As the exhaust gas cools and it's speed slows, the pipe size does not need to remain as large all the way to the muffler out lets. 2-1/4 " pipe to exhaust 4 cylinders per side, is plenty large enough.

 

Dr Gas makes 2, 2 1/4, 2 1/2, & 3" X pipe kits.

They do now but back about two years there wasn't any in the smaller size.

 

Labor and exhaust ran me $150.00. That was header back, installing x-pipe and mufflers. Delta Flow Flowmasters Mufflers run about $89.95 each. Lost the price on the H-pipe from headman think it was about $125.00 with tubeing btw use Percy's Header collector gaskets. There the best I have ever used! I know I have put these up b4 but here are a few pic of them under my car again anyways. Good Luck!

 

heres one more

 

I was wondering, what is the advantage of the x-pipe ?

 

scaveging effect creates a little less backpressure on full throttle.

At the crossover point for both banks, there more access to both mufflers by all the cylinders.
This crossover point tends to quiet the exhaust a bit more as well as create a differnt sounding exhaust from what an H pipe does.

 

It gives your car a wicked snarl type sound. Kinda like indy cars sound. I think it sounds great. Back when I first took my Sprint to Carlisle, I put it on the chassis dyno that was there. During and after the first run, there were alot of people running accross the show field towards the car to see. I think it was the sound that got their attention. Its definately a totally different sound.

 

WOW! Look when this thread started...

 

Summit has 65 Stang header-back duals for 139. At that price and only 2.25" mandrel pipe, I think I am going to give it a try.
The driver's side pipe interferes with the gas tank from what I understand, but the smaller the pipe, the better the chances.
