Hey Jim...I think you may have been thinking of SuperTrapp.... You could adjust tone and back pressure by adding or removing plates.

That's it! Thank you |

The funny part is that Supertrapp came up with that design for airplane motors, and later on started doing it for motorcycles. It is an incredible design that dissapates the compressive wave out the sides, and it is done very simply. Hence you get the thump, but not the pop.

| Patience please, I've encountered a minor set back in the generation of the code for the machining but have just spent over $5000 of my own money to purchase new software and training, I should have parts off the machines by the end of May and ready for a full on production run by the middle of June as promised earlier. I am flying to Raleigh N.C. for a training seminar from the 19th to the 21st and plan on cutting pieces the week after and posting pictures of them mounted on a bike.
On a good note though I just found out last weekend that even though Victory will not acknowledge it the tips on the Vision and the Cross bikes have the same mounting dimensions so these tips should fit those bikes too! |

I think those will look sweet!!!

| Okay, okay, I was going to wait until I had perfected and fine tuned the machining but I should have the first set completely machined next week unless we get swamped again with orders for our regular product. I've gotten the lathe work done on the back side of 4 pieces (2 sets) and finished turning a second set of jaws for the lathe to hold those pieces to turn the second side (the side that you'll see when on the bike), once the lathe work is complete I have to machine a set of soft jaws for one of our precision Kurt vises to hold them to machine the openings that the exhaust will pass through and drill and tap the center hole for the bullet in the center. Machining the bullet will be a simple 2 step process. All told I am looking at 5 completely different set-ups between mill and lathe work and since I want to be able to offer a finely machined finish (the kind of machined finish you can have simply clear anodized because it looks so good) that will save polishing time prior to chroming and eliminate any other finishing needed to powder coat or anodize.
Bluto gets the first pre-production set since he designed them and then I plan a production run of 40 complete sets.
Patience please....................... |

Spirit Lake IA "Birthplace of Victory Motorcycles" | Excellent! Do post pics when you get a set completed. Any thoughts on whether it will change the sound of stock pipes? |

| Finally got some lathe time in this week, was going to do this on Saturday but our shop had no power due to a storm that created havoc throughout northeastern Illinois. Here are a couple of pics I took after the first side (back side towards the muffler) was turned.

scotts valley, California | I put a set of homemade gattlins on my Ness honkers and feel that they adversely affect my performance and economy. The total outlet area is sufficient, but I think the gas entrance side should be engineered better than just a flat plate with six 7/8" holes in it (including one in the center). Do you agree? |

20 miles west of Chicago. | I was just looking at the drawings and it occurred to me that if the short cone on the inside were made a cylinder instead, perhaps a little longer. and center drilled with a threaded hole on the side facing the inside of the pipe, the tips could be made tunable for different motor/exhaust configurations, a la "Super-Trapp", by screwing a disk to the cylinder and providing disks of various diameters to allow more or less exhaust flow. The problem would be that a considerable degree of expertise in exhaust tuning would be necessary and no doubt considerable experimentation to determine the diameters of the disks for various applications. This, I think, would be beyond the scope of the project, but interesting to think about. |

scotts valley, California | Yah, Kevin opened up the intake side of things for me when he X'd the bike. Arlen designed an exhaust system that would let gasses flow. Then I choke down the very end of the system with some good looking gattlins. Go figure...... |

| Still waiting to get lathe time to turn the second side, once the turning is finished the rest of the machining will go quickly because I have 3 CNC machining centers but only 1 CNC lathe. I really wish I could just devote myself full time to this and other motorcycle related products I am developing but we are a small manufacturing shop (2 employees besides family) with our own regular product line of cutting tools for the engineered wood products industry (think building products), and right now that end of the business has been picking up again. I had been hoping to use the time when we were VERY slow to prototype and perfect the production of these tips but now I have to manage inserting that development procedure into our regular production schedule.
All said, please be patient........ |

Spirit Lake IA "Birthplace of Victory Motorcycles" | No problem. Glad to hear business has picked up! We all know that development efforts take a long time. Most of us don't even know about a product until it is ready to sell . . . we just get excited when we see something soooo cool for the bikes we are so pationate about. |
