mufler change

March 05, 2018, 10:24:30 pm

Was crawling around under the coach and seen where the exhaust side of muffler where it attaches to tail pipe was burned out.
also on the intake side of muffler it had been bent and was leaking.
Can anyone suggest muffler replacement or repair. I would be concerned with welding on a 19 year old muffler probably make it worse than it is already
Thanks
Chris

Get rid of it and put in a simple walker resonator. I have done it like a few others and very happy and makes the engine compartment a lot cooler.

Put the resonator on and you will get more turbo pressure with quicker spoolup and I used 270 gallons less then I used the previous ten trips cross country. Wrote it all down every gallon and took the same route to visit the grandkids.

John how is the sound? I like the Idea of better mileage and more power but DW won't like it if it is much louder!!!
Also, what resonates did you use, and any guidance on parts would be appreciated.
Thanks

The links in Reply #1 (above) will provide a detailed "guidance on parts"...also lots of pretty pictures.

I used the walker one as mentioned in earlier posting. The late Dave M also used that one. It has given the sound a touch more "growl" but definitly not loud, it just sounds (healthier). Taking out the OEM muffler makes a BIG difference on heat in that area and the bed is way cooler after a trip

?
Hangers and a few elbows along with some stainless flex pipe are all that is needed. Very simple to do and did it myself , and I took that end panel off so I could sit on a stool to do it all instead of lying on my back. Definitly a sensible thing to do. Panel is simple to remove.

I had put the Aero AT5050XL on out previous 94 U225 FT with Cummins 5.9 230 hp engine, and loved it.
I am now thinking to install it on to our 03/295 FT with Cummins ISL 400 hp engine. Should not run in to any issues corect? I see that few others installed on such as 03/320 with ISM 450.

It is pretty straight forward on the ism. Lot easier to get at batteries on mine.

Did mine myself also. Looks just like Jim Cs. I also used the aero AT5050XL. Much cooler eng room.

Does anyone have any experience with the Jones resonator? I was looking on line and it specs. out almost identical to the Aero even uses the same 5050 number!
Thanks

I have used one, except for the name on it, seems the same as the aero except about 25% cheaper. Pic in reply #8.

Chris,

You have the hardest part done by getting that hunk of junk down and on the ground. Going back everything is a lot lighter and cleaner.

You may consider heat shield wrapping the muffler/resonator that close to a cooler .

So there is no welding done during Aero AT5050XL installation? plug & play / clamp & bolt on?

Right, might have to do some cutting of the pipe, but you can do that with a grinder or sawzall.

I would love to do this work myself (last time I had to pay). I just don't know what/how/where to order the additional parts such as clamps, flexible pipe, etc. Ordering the Aero AT5050XL is easy enough, perhaps where I order the Resonator would also have the other parts. Some one may have already listed that here already, I'll look.

I just took my out and laid on ground and eyeballed the new route I wanted to take and ordered the elbows, clamps, hangers etc. Then a 2 ft section of s.s. flex pipe I could cut and use as necessary, FYI, the flexpipe does not bend as much as you think it should. Try to keep a little angle on it [side to side] to keep away from ac condenser.
Having a side door that opens, sure makes it easier.

Stainless flex may require a cutoff disk as hacksaw blades don't do much to it.

Good point, I had some s.s.flex left over from another job. Plain old galvanized will probably last 20 years, and be a lot easier to cut.

I'm gathering up parts, ordered the Jones At5050XL (Amazon) it looks almost identical to aero JCUS has used one with good results so I thought I would give it a try, it is 79 and change on amazon and I get free shipping. The local Truck Pro shop wanted about 142 for heavy duty band that was about half the size of Aero or Jones
I bought 10' of 5 inch SS and looks like I'll have to buy 10' of flex. I plan to make the tail piece ( Cut-bend-tig ) instead of buying the chrome piece I like the polished SS better anyway. I plan to tig it all together that I can, will see how it comes out
Propman looks like I may have some left over if you are in the area
