Replacement Mufflers

8/17/2011

First off, if you haven't priced an OEM replacement muffler from your local Volvo, Kenworth, Peterbilt, Freightliner or any other HDT truck manufacturers parts department you'll be in for a Real Shock at the prices they quote you on OEM replacement mufflers!

Therefore, it is advised is to go with a quality aftermarket muffler from one of several high end muffler manufacturers such as Walker.
 

Walker Mufflers:

Walker HD mufflers have a 1 year warranty versus the limited lifetime warranty on their Mega-Flow mufflers and a 4 year warranty on their Noisebreaker mufflers.

From 5th Wheeler (Jon):
Based on the length of warranty, my discounted purchase prices through a friend that owns a muffler shop and last but not least after speaking with a Walker Online Representative about their mufflers I opted to go with a Walker Mega-Flow #22963 for the Weedburner Conversion on my VNL770.

 

From Mark & Dale Bruss (Mark):
When Red Rover needed a muffler replacement, I ordered a Dynaflex from Iowa80.  The price was the lowest Iowa80 had.  At idle, the Dynaflex has a throatier sound but when I am running, the exhaust is quiet enough.  In fact, when we first were running with the new Dynaflex, Dale had to ask if the Jake Brake was on.
