| how to make a little noise without losing horsepower or $$$$. simply cut a 2 in square hole above the rear chamber of exhaust, about 4 in ctr of end. once open you can see the internal pipe that leads to the external tip. drill a 3/4 to 1 in hole in this pipe. this will allow a straight shot though system, the key is to not drill a to big of hole, just enough to add rumble but not to lose low end horsepower. of course add a 3 in square cover for 2 in square hole . weld or rivet, or screw, I like screwing!. I ended up with a very nice sound, not to loud. and i still have my low end grunt with no backfire or fouled plugs, exhaust mfg beware: it only took 2 hours and a few screws. note: i used screws because of future mods or to revert back to stock if laws change, a nice crisp sound that isn't annoying. i will try to send pic's soon. if you need more detailed info: Captain13Ron@gmail.com | |

| Why wouldn't you just disconnect your cable running the interactive exhaust valve and let it just move freely and tack the exhaust valve open? Of course this would only work on the 12's but a lot easier. | |

Of course this would only work on the 12's but a lot easier. I think that having the valve open all the time would not increase pipe volume. I cant tell when my exhaust valve is open while riding so I doubt having it open all the time would make any more noise. Rons mod allows for a shorter path for the gases and hence more noise without screwing around with the valve or cable set up |

| That sounds pretty interesting. It would be nice if some one could do this mod, video record it, and throw it on You Tube. | |

| Gee that's more work than the mod! lol, ok when i get my hand's on a video camera i'll get er done. i think i might bore the hole out a little more anyway, i want it just a little louder. to give you an idea of loudness, lets say stock pipe on a 1 to 10 scale is a 4, and a jardine is a 10 (loudest) the 1 inch hole will result in about a 6 or 7. just enough to enjoy the rumble but not be anoying. so far with no ill effects, Captain Ron | |

| i would really be interested to see and hear this thing for real. i bought a stock pipe for my bike to send to drummer but my funds wont allow it right now and the stock pipes are getting cheaper if i did decide to get another one. whatever, i need to hear your pipe before and after, i could do this mod this weekend. | |

| I drilled at 3/4 inch, sound is a nice rumble but still on the quiet side. 100% improvement over stock for sure! | |

Im assuming this will work on a xb12x uly right? The exhaust seems to be the same, although i think captains bike is a xb12s right? I may try this mod this weekend, I too dont want to wake the dead but do want a bit more sound.. power is fine the way it is, i dont run it like a raped ape often and found it pulls just fine for my style of riding..
The questions I have are 1) What material did you use to replace the hole you cut out.. tinfoil? scrap metal? was thinking an auto supply store and exhaust patch kit for cars would work? 2) Any adverse effects of using screws on the top piece? Air leaking or screws coming loose? 3) Any mods needed to airbox or ecm? I'm supposing not, but want to get it all straight before I hacksaw the shit out of my pipe!, 
Thanks!!!! and if this seriously works should be maybe a sticky.. If I in fact do mine this weekend I can shoot more video then youll ever want..

Did this mod... not worth the time really.. absolutly no db gain at all.. when its Wide Open you can hear a little bit of a deeper grunt, but not much.. during tick over its the same old quite buell.. Kind of frustrated with the mod actually now ill need to order a new pipe to send to drummer since i hacked this one up.
I dont suggest this mod at all it does nothing but enlighten you to whats inside your muffler.. |

| hhhmmmmm this mod is competely reversable. in fact drummer will cut this section out when they modify the muffler. if you quote: HACKED THIS ONE UP. it sounds like you did just that. i will be pulling my pipe off today so i can open the internal hole up for louder db and taking pictures to show exactly what the mod should look like. it sounds like somthing is lost in translation? i can only speculate but i want to remind anyone thinking of prefoming this mod that it takes place in the rear chamber, if it was done in the center chamber there will be no difference in sound and you would in fact hacked it up! to markwoodief, i apoligize for not giving more detailed information about the mod. because it does work well if executed properly. i shoud have given more detailed information. | |

Seems like an awful lot of bullshit just to save the money from buying a pipe. They arent that expensive guys....
New bike - $11000 Pipe - Maybe $500 for most of you Do the math...... Louder isn't better.... |

| I just fail to see the point of doing this mod. Yes its louder, but come on... Also, you have that plate held on with self tapping screws. You are riding a 400lb vibrator. Whats stopping them from backing out? | |

| let me explain the purpose of this mod. it was only ment to be temporary. until i could buy a micron$$$ i used the screws because it allowed me to remove the plate to enlarge the hole, and later i could revert this pipe back to stock if needed, at that point i would weld the hole shut and weld the plate on. of course this mod isn't loud like aftermaket. but it is a little louder than stock. P.S. do you know anything about titanium force exhaust? price? preformance etc.... | |

Again I must repeat this does not work.. seriously.. I did this to my 2007 Ulysses last week, my work looks exactly as your pictures.. yes.. I reread each word, etc.. The sound was seriously not that much different.. Now.. what I can attest to and posted a video on youtube with, is that afer I tried this mod and was disatisfied, I went with home hacked up pipe mod #2, Cut the thing in three pieces removed all the junk and rewelded it.. I found a local iron shop in seattle and the owner was bored so we used his band saw for a clean cut and his welding eqipment to put it back together.. now the sounds is quite amazing, not too loud, but a great deep rumble.. really loving it.. So much so that I dont think I'm even going to order an aftermarket pipe for it.. I had a fellow uylsses rider that lives close by verify my sanity, he is absolutely thrilled with mine so much so that his is going on the chopping block soon..
Im not trying to knock you at all captain, seriously.... I realize were are each going off our own experience.. My experience with my Uly was a slight lower rumble during idle, a little more noise during WOT, and no difference at all in normal rev ranges.. just my opion.. my piep really sounds great now... so much so that i think i actually prefer this sound to any of the after market exhaust that ive heard on buells.. |

The headers dump into more or less an expansion chamber? Did you use any packing? That may be asking for trouble in the long run...but im no expert.

the header dumps down into the interactive exhaust system pipe which goes a few more inches then opens up the middle of the can, then I left the back of the pipe in as well about 3 inches on that one.. so I basically removed the walls on each side and all the center tubing, but left a few inches on each side and left my interactive valve hooked up completely as it was stock..
I dont see running into any isses at all.. I put the Hi Flow Air filter on, and adjusted the idling squares on ECMSpy and its amazingly a different bike.. really really smooth.. idles just under 1000 and the blinkers dont shake like they used to.. Hope that answers any questions.. |

| I'm also interested. If Im reading this right and using the digram captain13ron posted you cut through a few inch's in on each side of chamber B and pulled the three pipes out and welded it all back up ? How did you know where to make the cut's ? also a link to your video on youtube would be much appreciated. | |

| Captain, I just finished this mod on my 2005 xb12r and must thank you. I am very satisfied with the sound of my bike. Not too Loud, Not too Quiet, Just Right!! I used a 1 5/8 hole saw to punch the hole. I then wrapped my header with copper wrap. Sounds Bad AZZ!! Thanks | |

| has any one out there tried removing the hole piece of pipe in the last section of can instead of drilling it????? i'm thinking after looking at pipe diagram that it may work well and still allow for plenty of back pressure | |
