Extreme Southern, AZ United States | There is a true 2 into 1 exhaust for the Vision. There is a false pipe on the left so the bike looks balanced. Problem is that I don't remember who makes em. |

Jasper, MO | The stock Vision exhaust is a 2 into 1 into 2 system as is. What are you trying to accomplish?

To accomplish that, get the adjustable timing wheel, a top air filter, and a fuel controller. You'll be money ahead on performance per dollar vs any exhaust system change. When you want to go for the gold, add the cams and extend your rev limiter.
Spend money on exhaust system changes if you are looking for a different sound. Don't expect any performance increase from any exhaust change by itself. That isn't where the performance increases come from. They come from better air flow in, better fuel and timing control, and cams. You might even lose some hp or torque with an aftermarket exhaust. The stock system is a very good performer as is, and can support 135 HP, as Lloyd demonstrated with a 116 inch Vision running through the stock exhaust. It's not restrictive.
Try Lloydz adjustable timing wheel as a first step. That will give you your "little more hp and torque". Then add the top filter and a fuel controller if you want even more. Then the cams and a rev limiter extension if you want a lot more.
This chart is a Lloydz big bore 116 Vision running through the stock exhaust. He calls it his "116 touring package". "Performance without the noise". Check Lloydz website. http://www.lloydz.com/dyno.asp

kansas city, MO | I have the adjustable Timming wheel ,VM 1 cams, PC-V, top filter, big honkers, by Rylan. Just wondering if I could scrape a couple more hp without going to the 116? |

New Orleans, La, | You can get more without going 116 ci, but you will have to remove the engine to add the 10.8:1 pistons. The increase in compression compliments the other mods you've made and they support the heavy breathing pistons. IJS. BTW, you can get them in stock bore and save on the cost of bore and Nikasil replating which my last quote was 4-500.00. |

Where is your rev limiter cutoff set at? It should be at 6400 or 6500 RPM to get the most out of those mods.
Ask Rylan about adding the adjustable intake to the top filter.
