Alright i just bought this 85 chevy with a crate 350 in it and its running on open headers i needa put an exhaust on it and was wondring what the best muffler would be for it (fuel economey wise) i dont care about sound i do care about performence tho and MPG most importantly haha

If your not big on sound (loud) then go to a reputable exhaust shop and tell them that you want the most performance and mileage, they will probably tell you to do a nice single exit with a large welded muffler.
