I liked it a lot and thought I would swap out the cheap FM knock offs. which do sound ok on my truck and are not loud but not the tune I like.



Magna Flows are cheaper knock-offs of Dynomax Ultra Flo welded - they used to be called "Race Magnum" series. They don't do ANY tuning at all as the exhaust passes through. To me, they sound FLAT, but get louder under WOT.
