    Can we eliminate the 4TEC waterbox?

    No expert in this dept., I know we need some level of back pressure, but is this possible?

    I know of two people that did this.... no make that three and all three of them went back to the water box quickly.

    It's deafening loud. Your much better off with an open style water box.

    Glen running a straight pipe on your 4-tec would certainly do it. Wear hearing protection though

    Want to set one up for Skipp, he is to blame for all these noisy Ultras

    I ran this setup and can assure you it is loud. Jerry is correct ear pertection is advised. You want have many friends.

    I then went with the shorty mufler.

    I will be running a shorter gutted mufler this summer.

    Go with the Gibson...just a straight through muffler with water added. Loud, deep sound, very nice. I just happen to have one for sale.
