It will be very helpful if you list a name (just first name if you'd prefer that), your home base, and your current location.

Luke is going to be your best bet he may have outlet now,Nelson hasn't made that muffler in 25 years the Y at the bottom it sits on is even harder to find now

good luck

Unless you are running the original N55 injectors, the original muffler is really stuffed up. Making a new exhaust system out of a better flowing muffler-like 5" will better facilitate pushing the engine up to 65 or 70 injectors.

When I turbo'ed my engine, I discovered very shortly that the big stuffed up muffler (even though it was 5") didn't flow. I went with a Donaldson 5" oval with inlet and outlet on the same end that is rated for turbo. Now has a nice exhaust tone to it and it actually runs cooler. Good Luck, TomC

We are not turboed but like the idea that it runs cooler. APPRECIATE YOUR INFO

Please take a couple minutes to update your profile with more information so that we can better help you! There may be a busnut in your own back yard, so to speak, that can direct you to local sources for parts & service. An example is the signature line here at the bottom of my post.

Simply click on Profile in the menu bar, then Forum Profile Info in the drop-down LH menu and follow the prompts. At least a first name, home base city/state, coach make/model & powertrain goes a LONG way towards helping us help you.

Be aware that you don't have to have "exactly" the OEM muffler to pass inspection. Most "inspections" simply require a muffled exhaust system, thus almost any style will fill the bill. So-called "turbo" mufflers are designed specifically to be downstream of a turbocharger and generally have very little internal restriction for increased flow in addition to decent sound dampening qualities. As TomC mentioned, Donaldson is one of the major suppliers, poke around thru this catalog link to find something that will fit:

Welcome to the madness, btw!!

That is the TRUTH about freeing up the exhaust, Many have eliminated the muffler and replaced it with a resonator IF YOUR TURBO'd, sure makes for much cooler bedroom and does add noticable improvement in getup & go.
The key is if you have the turbo, a non turbo would not be good for the noise factor.

I would try and find a used GM muffler those things are not fun to try and refit another muffler in that space with the Y at the bottom and very expensive new a friend of mine had a new muffler and wye with the clamp he sold for 1500 bucks. If I remember right it has a 6 or 7 inch inlet from the Y flange

Yo 62 4106!

Here's a quote from Tom. I'm using this muffler, it's a tight fit, but it works. It's not a plug in play, but a good welder can get it done in less than a day.

Donaldson part number- M120131. 5" inlet and outlet same side, 10"x15" oval, 30" long over all, 30lbs. It's not a quiet muffler-really rated for turbocharged engines, but it does put out a nice sound. Good Luck, TomC

Good information. We really needed that. Thanks for your help.
