I’ve always had great experiences with the dynomax ultraflo. They don’t have any sort of drone and are quieter than my old flowmasters. They’re 3in diameter but you wouldn’t even know unless you’re wide open.
This guy actually knows what he is talking about. This is the most counter intuitive thread I have ever read in my life. Taking Dynomax mufflers off to put flowbastards on is like trading in a clean 9" **** dick for a herp infested 3" model. Flowmasters announce your small penis in epic fashion, while they kill hp, drone you to death on the highway, and rust out in 3 years. Do step up to the Ultraflows; they are worth the money. I have had several sets of Flowmasters installed by previous owners, so I have been there. I have had the same set of Ultraflows on my Mustang for 21 years now. You could take a rag and bottle of Windex to them, put them back in the box, and sell them as new. That's how good the build quality is. Is there any way I could be more clear about my position on this?
