The muffler that came with my car is loud and hanging down so it has to go. I went on Summitracing.com and and see some options. Do I want to spend $100 and get a Flowmaster or spend $20 for the summit no name brand any thoughts?
Where is the muffler located? Does the car have a catalytic converter?
A “turbo” muffler from Dynamax (Walker) is also a possibility? Flowmaster’s are LOUD too.
The current muffler is just in front of the rear bumper (too visible). I’m thinking of moving it forward under the passenger seat where I think it belongs. The muffler is kind of small and loud. Flowmaster’s can be loud but some models are not as loud. I’ll look into the Walker brand to see what’s available, thanks
No cat not sure cats were around in 1974 the year of my donor.
The Pinto, Bobcat and Mustang II had the muffler as the last part of the exhaust system, except for about 5″ long down-turned tail pipe.
Two small “cherry bomb” mufflers in the system will quiet it down as long as you have enough tail pipe behind them. Even one will quiet it down if it’s closer to the engine and the tail pipe goes out the back of the car.
What ever you do, good luck!
1977 and up had first generation, inefficent cats. So, you probably don’t have one.
Pink,
I installed, per your suggestion, a dynamax turbo muffler this weekend sounds great so far in the garage.
thanks for the advise.
Tried also to pull the trans this weekend out the bottom, to replace the flywheel. No way to separate the engine from the automatic so I think my only alternative is to pull the engine and trans as a unit out the front. So this project will move to the bottom of the list until I have the time and space. So if I grind a little on startup I’ll just say I gave it a shot and will get to it some other time. Hope to title this in March and on the road in April.

Great news about the exhaust. Bet it sounds great.
Now you know the dilemma I had when I tried to pull my 4 speed out the bottom. In addition to pulling the engine/trans as a unit, I had to remove the floor hump to get the trans up high enough to pull off the trans crossmember…what a nightmare!
My BCW crossmember was welded in place. I cut it out and made it a bolt-in.Your CMC uses the OEM Pinto crossmember if I recall building the Ford based CMC TD I had. I guess you can’t get at the bell housing bolts from up top then lower the back of the trans to get the lower bolts? You can get at the flex plate bolts through the starter hole (after removing the starter).
You got it right I got all but two the two top most bolts holding the trans to the engine. I could feel the heads of the bolts but no way of getting a wrench in there.
Will get to this flywheel some day when I can’t stand the starter engagement noise any longer. Need to add the auto trans fluid and take it around the block to hear the muffler better. I’ve got other small stuff to work on.
How about a couple of well placed holes in the firewall to access those two bolts?
They’d only have to be large enough to clear the O.D. of the socket you use.
You could cover them with plugs. I did this with a race car and used a Unibit to make neat holes.
Now that I got it all back together again 🙂
Great suggestion but can I use a hole saw 🙂
I’ll have to look and see could be a little difficult getting everything lined up. Small peep hole first to see if I get close. Thanks for thinking out of the box.
It certainly would be easier then taking the whole frontend apart.
