I'm replacing the exaust pipe and muffler on my '59 f250. The old one has rusted through. It was not stock and exausts under the bed rather than out the back our out the side. Is this a problem? Guy at the parts counter says this is not a problem, and it sure is easy to just replace it with a new one of similar dimensions. But then why would Mr. Ford make so much effort to always exhaust out from under the bed?

 

Two reasons I can think of. First, I would like the exhaust gases to get as far away from me as possible and second, if they're are let go under the bed they can get trapped under there and leave a sooty residue, and I suppose there could be a chance for them to come back into the cab while idling at a stop.

 

Most vehicles you see ,will have the exhaust running to the back bumper,so the exhaust fumes, carbon monoxide,would be as far away from the driver/passengers as possiable.The older motors usually ran pretty rich ,mis-fired,ran a bit uneven at times..adding to the poor air quality at the exhaust tips.
When parked and idling, that exhaust collects under the vehicle,adding to the nausea, it's not too bad on a higher truck , because it gets some air flow-the space is open for air togo thru.
As long as your moving...no big deal.
there's also the cool factor..Zoomie headers,Lakes pipes, open headers, again, as long as your moving , no big deal, but you dont want to have to stop.

 

Yeah. I guess I was thinking that too. Stopping is already overrated and breathing my own exhaust fumes won't make it better. Right now there is a huge hole in the bed, so I suppose it won't be a problem until I fix that.

I'll see if I can get a pipe bent this week.

 

Rusted exhaust, holes in bed.Reminds me of the time my oldest son came sliding into the driveway,sideways at top speed with the back seat of his mustang on fire.Man it was pouring smoke and flames like you would not beleive.I,m standing in the yard taking all this in while son no.1 is shoving the garden hose through the back window. When calm finally prevailed I got the whole story,I d@#mn near had a stroke from laughing so hard.Heres the deal-- take one rusty muffler add one rusty floor board- mix in a real good backfire and hope you are close to home or the nearest fire station. Honest to God it happened just this way. Mark. btw. the stuffing in those seats makes real good tender if ya ever need a fire real quick and theres a S,tang near by.

 

At some point some mechanic ran the tailpipe on my '54 F-100out the right side just in front of the rear tire. It sticks out of the back of the running board by an inch or less and it has been run that way ever since. I have had no problems with fumes in the cab. It is neat when I am driving on a bridge or near a wall on the right side, you get to hear the rumble of the Y-block.

 

That does seem like the easiest route. If I go back to the tail, is it supposed to go ove or under the axle?

 

It goes over.

 

I went with abe's suggestion today. Looks fine sounds great. No fumes. Thanks!

 

My 78 F150 is how Abe has his truck. Mine comes out both sides ata 45 before the rear tires. Driving next to anything, you get to hear how loud it really is, lol.

 

Well Im not alone. My 78 F250 has the pipe turned out by the right tire, in front of it I should say. I never get fumes.
