Cat exhaust Leaks
I noticed a slight exhaust noise while underway Sunday, driving
beside a wall. Got to looking under the bus, noticed some of the metal band clamps that join the sections of exhaust pipes together are either leaking, or the exhaust pipes themselves are maybe slipping out of place from under the old bands. I was thinking of taking the bird to a local automotive exhaust shop, and having the old bands removed, and everything welded up nicely. There is also a hanger or two that needs attention. Also while there, I have heard some talk on the forums about people removing mufflers for a little more get up and go. We do not have any type of emissions in Florida, so that would be of no concern. The noise level is reportedly not too much louder. Has anyone removed the muffler and seen any difference? Any thoughts of welding the exhaust VS. New bands? Thanks for your help!

Cat exhaust Leaks
I am guilty of removing my muffler, and increasing the pipe size to 5" from the
down pipe. I moved the outlet forward so that it is about even with the front of the gen set. Works well and it's not any louder inside the coach. A little noisier out side, but that's all good.

Stephen: You might want to phone that exhaust shop before you make a
wasted trip. Most of the big chains (Midas, Meineke, etc.) do not work on big units. You need to find a big shop with either a pit or one of those behemouth hoists. You could ask one of the truck dealers where they send exhaust work. A good shop will have a big bender or at the very least a selection of large U bends . Bruce 1988 FC35 |

Cat exhaust Leaks
I had some leaks in my heads which DD (8v92) took care of I got a
muffler custom made as BB did not havve the part. looking into the muffler there was not much to it, I would be surpized if my Bird would move much faster without it. I used a truck repair place to handle replacing the parts that DD did not.

Anyone know the Old Ford #?
NAPA might be more apt to pull up that # than a Sterling #.. Thank you Stephen H 81 FC-33-SB Plant City, FL _____ From: wanderlodge@yahoogroups.com [mailto:wanderlodge@yahoogroups.com] On Behalf Of John Sent: Saturday, December 02, 2006 6:34 PM To: wanderlodge@yahoogroups.com Subject: [wanderlodge] Re: Cat exhaust Leaks When I went looking for the gaskets, I was sent from the Ford dealer to the Sterling dealer, as Ford no longer handles those parts for the trucks that used the 3208 Cat engine, unless they still have some of them in stock from the old days, that division of trucks was sold to Sterling, at least that is what the old Ford heavy duty truck dealer told me. Caterpillar does carry them, but I'm not sure what that part number is. I have no idea what the NAPA dealer will tell you, as I don't have a part number for them either.
