Size DOES matter when we're talking about mufflers. Black Widow's Big D muffler is in a class of it's own at almost 22" long and width of 7 1/2". If you're looking for that aggressive Black Widow sound and "size does matter", this is the muffler you need! All Big D mufflers are backed by Black Widow’s Lifetime Limited Warranty. Go to Warranty for details.

NOTE: Because Black Widow mufflers are universal and not a direct OEM fit, we recommend installation by a qualified muffler shop.
