| I currently have the thrush mod on the bike I like it but I was wondering if anyone has straightpiped their vision. I have been thinking about giving it a try, I really like loud pipes so I figured I would ask before I did it. By the way I have the upper air filter and a vfc3 on the bike. Thanks Dwight. |

New Mexico | I'm basically running straight pipes. Bought S1L2, then removed the baffles. Believe catalytic converter is still installed. Some minor popping on occasion, otherwise runs great, and mpg is about what everyone here is getting.
I think my pipes sound great! Loud, deep, strong rumble. Really shows off the strength (through sound) of the 106. My last bike was LOUD, and had quite a few folks tell me it was too loud. Some refused to ride behind me, saying they were obnoxious :-)
My Vision is LOUD, but nothing but positive comments.

my guess is, you'd be the first, though the other day when I pulled my mufflers to replace the belt I could resist cranking it up one time and giving 'er a blip.... I like my mufflers... |

| Thanks for the input, I think I will give it a try and see how it works out. I can always put my thrush back on. I am going to use some 2.25 pipe and I may taper it down depending on how the sound is and how much back pressure I may like to have. I had a 2into1 on my KP and I ended up running pipe from the collector to the tip so it was basically a straight pipe and it sounded great. Thanks for the input. Dwight |

Anderson, IN (48mi NE of downtown Indianapolis) | You could put your stereo on ebay. I'm sure someone has a bad head unit or speakers they need to replace. |

| Well we will see about how loud it is, I think by the time it runs through a 40" pipe on both sides it will mellow the sound some. Also with the pipe exiting so far behind the riders I would have to think that much of the noise is behind the driver. I hope to try it out this weekend. I have to go and get some pipe and then try. I will report back once I have done it. Dwight |

By your statement that the long pipes will put the noise behind the riders you are implying that you are not doing the mod to make noise for yourself, just to be a pain in the a-- for the rest of the earth's population. |

Rockford, IL | I might possibly be a bit wrong but would removing the mufflers reduce the backflow pressure enough to risk running the engine lean?
If it was me I wouldn't be doing this until I talked to someone "in the know" on the 106 engine like Lloyd or Kevin or similar.
I wonder if unhooking the ECM for a few and plugging it back in would help "reprogram" it for the new setup? |

Loud pipes save lives.
I know some folks say no, but I have been riding for 30+ years, have always had loud pipes, and know the impact mine have. Sure, cars are quieter now, but some sound still gets through (I own a 2007 vehicle, and can still hear pipes). Plus windows down, convertibles, sun roofs, older vehicles - All allow for noise. I know when I blip that accelerator it works better than my horn in most situations. And sometimes in high traffic situations I keep the rpms up over 3k for periods of time to make myself heard.
I see heads turn.
I see people brake.
I have seen people in my mirror suddenly look up from texting when I am loud on deacceleration.
And as I said, I do have a cage. I hear pipes.
So is for safety, not to be a pain in the A$$... That's just a side benefit

I had the same concerns, and although not the 'definitive' answer-man, my dealer told me it was not an issue in my case.

| According to the Hurt report is was determined that 77% of motorcycle accident hazards come from in front of the rider, while only 3% approach from the rear. What's interesting here is that motorcycle pipes direct the vast majority of sound backwards where the least danger is, so for loud pipes to be truly effective safety measures they would need to be pointed forward where the greatest danger lies. That doesn't do much to support the proposition that loud pipes are a safely factor. The other serious problem I have with this supposition is that it is, at best, a secondary safety measure, not a primary or proactive measure. Assuming that the other driver will act with caution once you have identified your presence by the sound of your bike roaring up from behind is foolhardy at best. That's like assuming that if you were to wear a bright yellow safety vest, or full riding gear, you can relax because now you're protected! Lets face it, the best protection you have is that 3 pounds of grey matter between your ears, that and a constant awareness of your surrounding, and acting on the supposition that the rest of the motorists in the world are all idiots and its up to you and you alone to ensure your safety on the road. Relying on the other guy to act reasonably or safely just because you're making more noise than those around you is just asking for trouble! |

I agree with most of what you are saying, John. Grey matter is your best protection.
Although I personally think they are an important safety feature, perhaps we could agree some portion of the 3% of accidents from the rear might be prevented by loud pipes?
And some portion of side accidents?
So loud pipes could be a mitigating factor in helping to prevent some accidents?
That's reason enough for me.

Rockford, IL | Dwight - 2011-11-03 10:48 AM as far running lean, that is where the vfc3 comes in handy..and the noise well, I like it..D The problem is knowing what settings to use on the VFC3. Don't think I'd want to be guessing or simply setting the mix to what I "think" will work or sounds/runs good or whatever. As mentioned....I'd touch base with Lloyd or Kevin and run it by them and see what they think will work. They are both fairly easy to get in contact with. |

+1 glighto11 (don't know about the fuddy-duddy thing though). Don't get me wrong...I like to hear my scoot as much as anyone, just not loud to the point of scaring little kids and to make the general public curse me under their breath.
"Loud pipes save lives" is the biggest load of crap. If that is true why is it when I move to the front of my "straight piped" H-D rider friends going down the highway I don't hear them anymore? |

| Loud pipes don't save lives but it does piss people off which usually reflects in the voting booth when some peice of motorcycle legislation comes up. |

Brighton, TN | Dwight, enjoy the project, it is something to pursue to challenge the brain cells. sometimes I do wonder why the Naysayers wind up chiming in because you are a Egotistical Maniacal Homosapien that actually loves the pounding a V-twin rattles down into the core of your body, physically. Nothing like the smell of Nitro Methane and shorty open headers on a top fuel dragster, then the sound rattling and emanating through the core of your body when that beast lights off. OOOHHHH RRAAHHHHH! Man o Man feel it now.
However, I do enjoy that sound as much as anyone, but I rode a guys HD Fatboy with straight Pipes and I don't know how he rode the thing. When I rode it, twist the throttle and I was trying to grab my ears, because it was so $%^&*() LOUD!
I prefer the radio, and cranking it loud while cruising. What I would much rather do, is put one of those electric cutouts on the exhaust for when I really wanted to show off, and then close it back so I could turn the radio back up. Then again that's me, not YOU!
Rock on and Git R Dun |

| I enjoy straight pipes too, that's why I kept my Harley. After my last ride was spent behind a Harley with them, I'll never take on a ride more that 50 miles in a group.

| I would give a try and see what you think personally. In my try it was a little annoying after a few rides and I couldnt hear my radio like I wanted. I ended making my own mufflers and was able to reach the perfect happy medium between LOUD and it sounds ok!! HAHA! You just dont want to run to lean and lose power. Sometimes they sound good but wont run! Sounds like another brand...... I wonder which it is. |

not far from hustler wisconsin | I took the baffles out of my 09, made a pair of end blocks of aluminum, with counter sunk set screws to hold the straight pipes in place. Then I started drilling 9/16 holes until I got the sound right.the more holes the quieter. I stopped with two on each side.the bike sounds great, is not hard on others, but if I whack the throttle hard enough, it can be obnoxious. It breaths great, g ood throttle response, awesome high rpm power.
The catalytic converters I left in, Lloyd said they alone are enough for back pressure.
The pipes themselves I let extend from the blocks just as far as the end of the slash cut. The exposed part I painted black bbq paint.I am very happy with this mod. |
