MagnaBLOWS on the 3L, it will sound extremely horrible. I had one for almost a year in 1998 then a blow out. I ran the 50 series deltaflow big improvement on the 3L with 2.25 piping from the catback, sounded really good. After 3 years I changed to the original 40 and changed the whole pipe size to 2.5 and it sounded very good. After 7 years I got tired of the tin, raspy drone on the hwy I drive alot of hwy miles and even in 5th gear it really started to bother my migraines alot. Monday of last week I bought another super 44 and put it on then I just got back from taking a 2000 mile trip in my Ranger and the 44 sounds alot better then the original 40 did. It is deeper, better sounding and it still has drone on the hwy, but not high pitched like the 40 has.The only difference between the 40 and 44 is the 44 is more bassier and deeper then the 40. The 40 is more louder and high pitched.
Between the 3 Flowmasters I have used in the last decade I choose the 44 with 2.5 piping from the catback to be the best setup for the 3L...
