news on my most recend exhaust de-grade...i took of my stock muffler. havent driven it yet but it sounds like it will make a bit of a power difference...it was one of those big round silencer things that goes at the very end of the exhaust system. I am now running 2" straight pipe...i have a modified 1bbl carb and needed to retard my timing and stuff for it to run good, sounded like crap at first before i tuned it up...now its the most amazing thing i've heard yet. It sounds biggggg....at idle it lopes and has a nice deep sound, and when i rev it up i dont get that farty/ricey sound...it actually rumbles as i rev it...beautiful...and when i start it up it growls before it does the lopey thing...wow...i am truly amazed...hope it performs better now too...I'll find out tomorrow


got my 78 merc with a 250 I6 and i love it.
