I know this has probably been asked quite a few times but searching these forums can be tedious! Anyway, I have a 04 4.7 Ram, I want to replace the muffler. does anyone have any info on 40 series from Flowmaster, like which one fits! Any info on Magnaflow would be cool as well, Gibson does not return e mails! TIA
Also I believe the pipe diameter is 2.5" in/out single.
