welcome to join in. I have Brullen and love the sound. Smaller cans can be ordered along with different size tips -- 2.5", 3", 3.5" or 4". My Brullen is 3" X-pipe piping with straight through mufflers and resonators. Notice the construction inside the tips in ZBlacktt's pictures. There is a screen with sound absorbing material behind it. I think this is what gives Brullen such a great distinctive sound. When ordering, you can order loud or quiet. Mine are the quiet type which is loud enough. The loud version must be as loud as B&B's. If anyone wants to join in on our group buy, email me and I'll hook you up. t_mthlvg@yahoo.com
