:'( I have a straight pipe spit into duals. I pull a gooseneck horse trailer and the sound is deafening. (I love it but its too loud you cant hardly carry on a conversation in the cab.) I have stock pipes what is a good free flow muffler that will fit the pipes and not empty my wallet. Thanks

 

Dynomax makes a good kit for a reasonable price. It includes a muffler and 4&quot; tailpipe and chrome tip. It hooks up just after the resonantor. The muffler is supposed to be a good fit for flow and noise reduction and the 4&quot; tailpipe is more than adequate.<br><br>Good luck.<br><br>J-eh

 

I can't seem to get a link to work to Dynomax's site. I'll keep poking around.

J-eh

I used to things were loud, then I started building big block chevys and breaking in the cam with open headers, now nothing is loud-lol

 

You might want to try the Magna Flow, it's free flowing and sounds good. <br>Big dawg

 

I've got a 4&quot; straight thru muffler sitting in my garage. I'm debating on selling it.

 

Slightly off topic, but here is one good reason to have a loud exhaust:<br><br>https://www.dieseltruckresource.com/...;threadid=8467<br><br>Rich

 

I have my stock convertor, with dual 3.5&quot; into 6&quot; long mufflers that are inside the 6.5&quot; tips. I get a cool tone around 2000 rpm.<br><br>jt

 

Has anyone tried flowmasters<br> ???

 

I did this and the exaust noise is all gone. It is just about as quiet as stock. Worked on mine.

I got one of these on my truck now, almost as quiet as stock but free flowing<br>http://www.dynomax.com/ultrafloweld.stm<br><br><br><br>I was disapointed, I should have tried one of these <br><br>

 

If you run the flow master long enough it will be a straight pipe..LOL<br><br>Notice all the fiberglass in there??? Well thats a great diesel particulate filter isn't it... After some good smoke shows and heavy loades that muffler should weight about 100Lbs and be full of soot. <br><br>The diesel application mufflers are only filled with steel baffles and not fiberglass for this reason. The Dynomax stuff is supposed to be pretty good.<br><br>J-eh

 

Lil dog, I may have misread your post but Flowmasters have no packing they are chambered. So I would think that they would be an ideal muffler for a diesel set up.<br><br>John<br><br>
