This is the new 4" from the 40 series flowmaster to a 6' tip. Start up and rev, then idle and better look at it installed. system runs 2.5' duals to a dual (myself made) inlet 40 series flowmaster, then single 4" out of flowmaster to the tip, tip is 6" cut down from a big rig stack. all welded and installed by me.
