aknavy Posted July 19, 2023 Report Share Posted July 19, 2023 Had my exhaust converted to a weed burner to accommodate a big drom box a couple years ago. In the conversion, no real muffler was put on. Not that big of a deal till you do multiple long travel days in a row, and the wife gets tired of listening to the truck. So - any recommendations for a muffler to add to it? There's alot of room under the passenger side. Anyone run a muffler on a weed burner, and does it make a noticeable noise difference? Would I be better off taking the seats out and running Dynomat on the floor?

HERO Maker Posted July 19, 2023 Report Share Posted July 19, 2023 I/ would imagine the Dynomat would help. I had the muffler shop change mine out after they installed one that sounded like I was at the drag strip! I liked the new one a lot better.

Yeah, ours is pretty loud, especially if there's a Jersey barrier close by. It's bearable on short travel days, but long ones get annoying.

Darryl&Rita Posted July 19, 2023 Report Share Posted July 19, 2023 Walker, along with others, build a muffler with end in/out connections. Go online, or pull up a stool at the local parts house, and start browsing.

Darryl&Rita Posted July 19, 2023 Report Share Posted July 19, 2023 I don't remember the particular model we have. Internals reminded me of the old Thrush mufflers, with stamped scoops to funnel the sound to the matting. Turn it around, and it's instantly "better" for kids.

rickeieio Posted July 19, 2023 Report Share Posted July 19, 2023 I've had the good fortune to replace 3 of those type mufflers in the past few years, one on a VNL, one on a Mack, and one on a John Deere. I bought all of them at my local Mack dealer, who treats me well. All were well under $100 ea. I would think any truck parts house would have what you need. A little time with a hack saw, and a wrench or two, one muffler and two band clamps and your bride will thank you.

When I paid the have the exhaust converted, I assumed it would have some type of muffler, and realized later that it did not. Now, after two years of running around the country we're tired of the noise.

rickeieio Posted July 19, 2023 Report Share Posted July 19, 2023 I don't know the particulars on your truck, but some use a 4" pipe from the turbo to the muffler, then a 5" outlet from there. Our Mack and JD both were configured that way. I've only seen the 4" on motors of 13L or less, but then, I haven't seen them all. I really like the install in the pic. Nicely done. The level shows they cared.
