I have fallen a little farther behind than i expected in getting the engine fired up but am finally ready to order the Dyno Max's.How long are the mufflers you reccomend? They make 14's 16's 17's and 20's.The part number for the 20 incher is the one listed in one of the test you linked to but 20 sounds pretty darn long but maybe thats why they flow so well. Hate to get the big ones if the shorter ones flow as well ,just checking to see what you have .Thanks
