Hi Guys, Just wonder if you have a preference for muffler location. Under the front seats or rear seats. I think there is a difference in sound depending location. I was told under front seats will give a deeper tone, (longer tail pipes)? I'm running a 351C with Boss manifolds, no room for headers. 2&1/2 inch exhaust pipes will be used. Will dump down behind rear tires. Thanks for any comments Terry
There are hangers made for the mufflers to connect to under the front seats. when I installed mufflers I was more worried about securing them and having a secure exhaust system that didn't rattle or need new brackets made. I use straight through Hooker Aero chamber and they can be throaty. Not like some of the higher priced mufflers though.
I always believed that cars that had the mufflers closer to the exit sounded better. I had glass packs in the factory location in the day and they would "rap" on acceleration while other cars would "rap" on deceleration. I have my mufflers under the seat now and the exhausts exit behind the rear wheel. Personal experience and preference, no facts....
i am going to put mine under the back seat.i picked up a exhaust kit for a 65-66 mustang.looks like it will work with a few mods.this kit comes with all the hangers,will make it simpler to install.kit came with flowmaster 40's.thinking this will be too loud.what are you guys running?i want it quiet
18" magna flows , 3" in 3" out. Mounted as far back as I could to route tailpipes over the rear end housing.
I made my own tailpipes from flowmaster 2 1/2 universal kit.
I found if you dump the exhaust in front of the axle the drone will drive you nuts, almost to the point of wearing earplugs on a 50 mile drive.
My engine was a modded 460.
I ran my pipes down the trans tunnel area, with a balance pipe near the rear of the trans, mufflers mounted in the floor pan recess under the rear seat so they are up nice and high, tailpipes all the way out the back, sounds nice and throaty, also nothing hanging below the frame so when I'm fully loaded, no chance of getting them hung up.
I am running 2" Turbos beneath the rear seat, tail pipes over the axle turning out and down exiting behind the rear wheels. Almost too quiet!
I have glass packs at an upward angle as it goes over the axle.

Almost too quiet is not good enough. You'll have to get under there and make some holes in the pipes or something so we will know that your'e coming. HA HA Jay
Is there any reason NOT to use a balance pipe? My 60 C***y Impala didn't have one but I know others say they are a must. On the Ranchero I was going to run the pipes just inside the frame rails meaking it difficult (but not impossible) to fit a balance pipe.
I was always told the H pipe or balance pipe gives more low end torque. I know all of my Mustangs had the H pipe on them.
A couple of thoughts on exhaust systems.
I agree, that the drone is unbearable if you exit the exhaust under the vehicle on a road car. It's better out the back, but at least make it over the rear axle, and out behind the rear tires.
On my roadster, I built a 2 1/2" system using a home made "X" pipe made from two 90's welded together at the radius. It worked very well.
I wanted the new system ceramic coated. So, I checked with my coater (Embee Coating, Santa Ana, CA) and they could handle anything up to 60" in length in their high temp ceramic oven. So I built the exhaust in sections of less than 60" and joined the two tail pipe/muffler sections to the "X" pipe section with "V" Band clamps. I was very happy with the clamps, and the satin black exhaust coating looked as good as day one when I sold the car after five years of use.
I have "smittys" on my 57 ,just inside the frame rails and at the same angle as the rails ,has a real neat appearance and they sound pretty good exiting under the bumper. I put a set of Flowmaster 40's on my brothers Mustang about a month ago and they are too loud!
Oh Junior 58 , you mention being fully loaded , what are you hauling in New Zeland ?
Barry, at the recent Muscle Car madness (that Tom Drummond attended while he was here), cruising of the complex was allowed (encouraged), I was known to go eight up at one stage (who needs airbags?).
Even when cruising six up (with a load of likely lads) I have scraped frame rails over our severe speed humps through the middle of town.

My car had 2 1/2 Smittys on my car when I bought it, everybody knew where I was!!! (Not good). When I replaced the 302 with the 390 I went to a 2" exhaust with the "Turbo" mufflers. I really did it to get the car on the road with a "base line" system. I plan on going to a 2 1/2" pipes with a cross over, headers, and TBD mufflers. I like the tailpipes exiting behind the rear wheels so far but.... still researching (reading these posts)! :003:
I've always liked the look when they exit behind the rear wheel with a turndown instead of out behind the bumper. I may change mine if there's enough room to go between the frame / leaf spring.
I took mine out to the bumper and put polished 2.5" turndowns on.
decided to go with the 70 series flowmaster mufflers,under the rear seat.will try to exit the tail pipes behind the rear wheels if there is room
Plenty odf room...my mufflers are under the rear seat.
One of two more...
Finally! :003:

That's a great looking car from what I see. Have anymore pics of it?
I have hesders on my 351c 4v in my 57. They are for a 70 Mustang with 351c...fit like they were made for the car, no dents, no dings...my mufflers are 3 inch pipes to 2 chambered flowmasters, dumps, no tailpipes.
All this exhaust talk brought back an old memory for me. My dad had a 57 Fairlane when I was 15 or 16 years and whenever I washed it I would run water up the exhaust trying to make the factory muffler rust out so it would be louder , I cant remember that it worked.
Wish I could put headers on my 351C but I have power RacknPinnion which gives me no room.
I am going to run a Porter muffler set up on mine.You can have them built to any size in length you chose and pretty much for $100 per muffler.
While in Detroit this past weekend, I managed to be at the Ford Motorsports display, they had a new HI-End Boss Stang flipped on its side to reveal the under carriage.The exhaust was X-piped and the mufflers were a Borla-Ford motorsports combo.But the mufflers were at the very back,exiting at the rear of the car under the rear bumper section.I understand this is where Vettes have theres too.I had a discussion with a Ford tech at the show and their testing indicates this is where maximum power is achieved.I wonder if this can be possible on our older cars?
I plan on using a Porter because of it's narrow body and custom length.

If you don't have a picture of that Porter muffler, then it doesn't exist.
Is is anything like a porter wall for tires? HAHA Jay
Oh Jay hahahaha
Jeff, that's exactly what I was taught years ago by a buddy of mine who built/raced sprint cars. He really knew a lot about every aspect of building cars for both street and track. And as long as there's room out back its my preference just as long as its not visible from behind. To me a crusty muffler hanging across the rear is as attractive as a full diaper on a toddler. Other than a set of fenderwells the only part of an exhaust system I want to see is a pair of tips.
Zap- :unitedstates:
Will check out that Mustang system when my wife's 2015 GT gets here.
Jay,
Here is the Porter site.Good People and I feel the best sound.Dig into the site and see the history.

Jeff
They look nice. Have you ever heard a car running with Porters on it? Are you going to place the Porters in the stock location or somewhere in the rear? If in the rear, do you have enough room without interfering with the fuel tank? This theory of mounting them in the rear sounds interesting.
Man I really like the Porter stuff. Crap, just when I thought I had figured out what I wanted its back to the drawing board!!!! It makes sense that you can make more power with the mufflers as far away from the engine as possible... the exhaust gases can cool, become more dense, and then can move through the mufflers faster with less pressure drop.
Jay,Lynn,
Yes, I have heard different cars personally and that is why I bought a set for my coupe.I have heard them on a flatty,Y-Block and of course a taxi cab engine(C**v)
Each engine gives a distinct sound and of course the sound differs on how much an engine is modified.The ones I have heard all have crisp rap at a throttle burst but mellow out to a cool burble at idle.Nothing annoying.
Lynn, I have not heard them on any FE motor as of yet,but I am gonna try to get a custom length set made to fit in the rear of my 57.(that's the plan so far)
Jay,I have a line diagram somewhere in one of my 57 Ford manuals that shows a 57 with a full muffler system and "resonators" in the location we are talking about.No where again have i seen this illustration or heard mention of it in any other literature.
the image shows the resonators to be about the same size as a set of porters, thats when the wheels started to turn.ha ha
I have seen the rear resonators in print somewhere as well. I wanted to put glasspacks in the back in 1965! I guess I forgot.... :003:
Lynn and Jeff
Honestly I do remember the resonators and they were toward the back of the car. They were in addition to the mufflers that were in the standard location under the seat. It has been a looong time since I last saw them or even gave any thought to them, and they were on 57 Fords in Mass. So Jeff I'm backing you up that they did exist for real. I also remember when people were bypassing them with a straight pipe.
Maybe it was just a Mass. thing but they seem to have just disappeared into time.
Rich is too young to remember those things even though he lived here. HAHA Jay
It shows the full exhaust system in the workshop manual, including the resonators at the rear. The tailpipes cross over the rear axle and then swing out to the outside of the chassis rails (so they are not between the rails and the fuel tank), so that would put the tips further toward the outer ends of the rear bumper (as per PDF image attached)
Yes!,That's the image.On my car the hangers are still attached in the rear at the outside of the frame.Thank you junior58 for posting that image.
That pdf is what I saw lately that I most recently forgot... When I saw that in the manual it reminded me of what I saw a long time ago that I forgot first. I KNOW I never saw those resonators on a real car ever!!! Maybe factory dual exhaust were rare. I seem to remember exhaust pipes on most cars being inside the rear springs mostly but I know I saw them outside the springs as well. Early model running production change???? Confusion reigns supreme!
Verly interesting (in Sgt. Schultz's German accent)....
Here's what mine looks like
Lynn....I know exactly what you're saying...I knew about them once, then forgot until the subject was just brought up. I can't even remember what they were for. One would think coming from Detroit they were to quiet things down, but I've got something in the back of my head that's telling me it was to add a "rumble" to the sound....as I would think the name "resonator" would imply.
Jeff...you ought to post that on the Hamb to see what the responses are.

I am not afraid of anybody pal.
As for the reason,that board would have ZERO idea of what we are talking about here,nor do they really care.
lets move on.
