Any muffler experts?

[M Barnett]

While in a muffler shop I spotted a nice looking stainless steel muffler that was slightly used. They said a fellow with a motorhome had it installed and then removed. To make a long story short, I bought it and sent an email to the manufactuer, Riker, with the PN to get info. After a couple weeks they got back to me and said, "Very good muffler and expensive. Do not recommend using an offset muffler on a diesel. " Thats all they said. Now I'm confused. Our stock mufflers are offset so I don't understand the problem? I already had the muffler put on and the reason I bought it is because I didn't want a loud muffler and this muffler while it isn't straight through, I could see lots of daylight going through. Figured it would have less back pressure than the stock muffler. Anybody that can shed any light on this?

Thanks

You're probably fine! My Banks kit came with a 4x3. 5 offset muffler. I got the bug for the 4" 21471 Walker straight thru muffler and 4" tailpipe and didn't gain anything noticable but noise. I can't see lite thru the Banks muffler so it's a good chance yours is better if it's a big case and 4". Craig

I don't think the offset is the problem. It's probably the fact that many offset mufflers are chambered, and chambered mufflers are a bad idea on a diesel.

The only good muffler is...

the one that isn't there.
