Exhaust pipes on 79 SN

Thanks gun-driver

I thought mufflers improved fuel economy and straight through just made you look an idiot on the lake and emptied your wallet

The weather will improve soon so people can get back to what they love

Plus 1!

"What is the gunnel on a boat?
Pronounced. gunnel. the word is properly spelt. gunwale. in standard Englsh. This refers to the upper edge of the side of a boat, and is usually used in the plural."
I asked about the stringers!! There are great sites that have ALL of the proper nautical terms.

Gap in the gunnels?

Yes, the carpet was on there it keep them from rattling and wearing through the thin wall of the mufflers. Didn't we suggest just replacing them with hose or tubing? Are the 4" muffles going to fit between the stringers?

We asked for pictures! Where are they???

Thnks for all the help in figuring out my problem.
I will sort the pics out tomorrow.
I have found replacement mufflers on skidim and then by the sounds of it I could revert back to corrugated exhaust pipe to fit to my manifolds.
A cheaper fix would be to copy other side which will become clear once I post pics

Matt,
We sure need pictures as requested. I'm totally confused and can't really follow what the problem is.

Many here use photobucket as a photo web site. It will automatically resize any picture loaded into it. Just set your personal settings.

By "baffles" I'm assuming you mean muffler. Sounds normal for a '79. I can't think of a marinization package that utilized elbows, certainly not the more common pcm's. Sounds like those were added. Sealant doesn't belong anywhere near this repair.

Get on a computer and reduce your pictures and post them- a description isn't going to be enough.

i have a 79 mustang i'm messing with the exhaust on right now. mine doesn't have elbows, just uses flex exhaust hose to go from the manifold to the fiberglass tubes. are you saying you crushed the "flange" on the fiberglass tube/muffler?

fiberglass baffles on a 79???

Having trouble uploading pics
File manager says they are too large and don't know how to reduce size on new phone.
Anyways where the blue fibreglassed baffle is tapered down to fit a rubber hose to the straight then elbow to manifold is cracked and damaged; the baffle tube is located about 2' from exhaust manifold.
I think the same happened before on the other side and it looks like they used a rubber reducer that was fitted over the blue fibreglassed baffle tube and connected to the steel tube then elbow up to manifold.
I thought the same would work for the damaged side
I forgot to mention the reason for pulling apart; there was a hole in elbow which had been fixed previously but leaked all last summer causing me to pump for around five minutes every morning on trips.
If I was to remove everything and replace with a s/s pipe and elbow would my fuel bill go through the roof or just increase a little, looking from the outside flap down the tube all I can see is a cut off elbow in the baffle restricting flow a little.

Thanks in advance

Matt

Thanks for the reply,

Is there some where I can purchase replacement baffles.

Otherwise I think I will copy the repair on the other exhaust.

I will put some cauking around the fibreglass baffle then fit the rubber reducer to ensure a tight fit.

Last night I started the task of fixing a leak on my elbow from the engine on my exhaust, which is shot.
When I removed the steel elbow and straight piece the connection to the plastic/ fibreglass baffle broke down. I noticed a repair had been carried out on the other exhaust at this point by fitting a rubber reducer from the fibreglass baffle to the steel pipe. I thought I would do the same.
After a nights sleep I thouhgt I would ask what if I took these baffles out completely and replaced them with new s/s pipes right to the transom.
Thoughts and implications please.

Thanks Matt
