I don't have the original original info on this but posted on a Jeep forum I am on. Several guys have stated that the home brew mix works very well!! Zach571

MY exhaust :cheers: :mrgreen: This is it, this is what I made. Pic on the bench, adding this cus the pic of it on the bike was too reflective and hard to makeout the actual shape of the cone. Installed Final product, all polished up :drool: Packed with FMF 4 stroke insulation. Has a really deep throaty growl to it, no louder than most other sport bikes with aftermarket cans. More power and seems through out the rpm as well and quicker throttle response (didn't notice it till the new exhaust). Other than my time, picked up another stock can for $25, SS will probably be less than $40, rivets, insulation was $12, so rather cheap mod :laughing6-hehe: Zach571

Anyone have any input on whether I need to retune anything?? I know it is fuel injected but rather primitive setup... Zach571

Well I have the plan that was in my head drawn up in CAD. Calculated the flats for all the cones and rings, just need to bring them into work to have them burned out on the laser. Then debur them, roll them, and weld them. Easiest would be to leave a brushed finish on all the parts but the can is already polished, so I should probably polish the end cap as well. Polished can with a brushed cone may look nice... Should all come together nicely. Only thing I do not know is how loud it will be...hopefully it is good the first time :blink: Pics to come. Zach571

Can't tell me I am the first one to gut a 5th gen can?! :blink: Zach571

Finally getting to the exhaust on my bike. Gutted the stocker today and this is what I found. I put film on it to protect the finish while I was working on it, thats why it is white. Notice the very end of the pipe?? It is hemmed over the end cap, then spot welded in 3 places. I ground down the bend of the hem and removed what was left of the inside of the hem. I drilled out the 3 spot welds and pulled the end cap off. Found this rusty SOB underneath that. welded a pc of scrap to that so I had something to grab on to. Took some force but the whole works slid right out. Has a few baffles, nothing too fancy, looks very restrictive. My goal is to be able to hear it but I do NOT want it loud and obnoxious, while possible gaining some power, not that it needs to be faster. So my plan is to cut an inch off the back of the can, fab up a new end cap with a perforated tubing welded to it, that will be wrapped in insulation and then slid into the can and riveted to the back of the can. I have access to perforated SS, several different hole sizes to choose from, and a roller. I am a lil limited on how tight of a diameter I can roll it, other than that I can make it whatever diameter I want. Could even make several different end caps with different sized tubing welded to them and try them out. Different hole sizes in the perf as well. For the end cap I'm thinking I can copy the basic idea of the stocker but have it either slide onto the outside of the can or to the inside, but not recessed like the stock one. Kinda makes for an ugly seam on the factory one. The baffle assembly in the stocker is all made of steel and is rusty, the end cap you see is just there for looks, that is its only function :fing02: The can is about 19 inches long, the inlet sticks into the can about 5 inches, as a perforated tapered tube that does not end centered in the can. I do not see an easy way to remove that, so thinking of making a slight cone for the inlet of my perforated tube, but the parts I make to add to the can will only be about 14 or 13 inches long. Any of us would be able to see its not stock at a glance once its done, but I'd like to keep the factory stamped HONDA and paragraph on it, so I can only shorten it about an inch. But as I said, I want to be able to hear but I don't want it to be "loud". What is a good source to get insulation from?? Zach571

PM sent, and I forgot to mention in there that the spanner wrench works great with my 929 in my 5th gen VFR, I have no way to say for certain that it will work on your bike (clearances and what not, just a disclaimer). If it doesn't work I could make a longer/shorter/kinked one... Zach571

Just to specify, the spanner wrench is for the 929 shock, not sure it will fit anything else, doesn't grab the stock VFR shock, thats for sure. I cut them out of stainless steel, 7ga. $10 a pc. As for the adjustment, I do believe I will be able to get to it, looks like I just need to remove the one panel on the right side and looks like I'll be able to get it just above the exhaust pipe. I have not yet tried to adjust it, so I do not know for sure. Zach571

I finally put mine in, with the reservoir to the rear it contacts some plastics and I didn't like that plan. I looked back at the beginning of this thread and saw that the original poster put the reservoir forward, so thats how I put mine in. I also made a spanner wrench for the 929 shock, if anyone needs one let me know. Any suggestions as to where to start with the adjustments on this thing?? I made two mounts, one the 42 mm and the other 40 mm. I installed the 42 mm first. The rear tire is barely off the ground on the center stand and the bike definitely leans over more on the side stand. My bike is still in pcs from a wipe out Fathers day so I haven't ridden it since. Zach571

I would say not an issue, if its walking around then your nut isn't tight enough. Once its tight it shouldn't move at all. Zach571

I guess I missed that talk, the idea of making an adapter and still using the stock mount never crossed my mind. I haven't put much thought into it, but I don't think that an adapter would be feasible. That makes for another bolt that could come loose or fail. You have to track down another bolt, my mount completely replaces the stock one and reuses all of the original fasteners. I'm not fond of adding another piece, more chances for failure. More than one way to skin a cat :fing02: As seen in this thread there have been several different methods shown that ended with the same results. Zach571 I like the look of your bracket and not grinding down the bolt head is a plus! Are you making more? I can, I won't be stocking them on a shelf though. Made to order. Zach571

My 12"/300mm caliper says that the 929 shock is 286.4mm, so a 38mm difference. All this is for a 5th gen, I do not know about how the others are setup. I made up a mount tonight, well did the actual forming and welding tonight, at 42 mm longer than stock. Dan, I'll be working on a PM for ya after this post :fing02: . It is made of 7ga/.187" stainless steel, but with a 10.9 bolt. Hard enough to find a stainless bolt in 10X1.25 the way it is, plus from my bit of searching, not an adequate strength available. The bolt is welded in, not going anywhere, all the welds are TIG welded. All I had to go off making this was measuring a new stock mount that I got at the dealer, my 929 shock, and the info on here, so I really hope it works. Dan is my guinea pig as I won't be able to put mine on, much less ride it before he does :mad: When I get to mine I will probably make up a few different lengths, or at least a 38mm to go along with my current 42mm. That way if I get bored I can toss in the other mount and see how it affects the handling, somehow I doubt that will happen but... Not that it has to look pretty but I bead blasted it when I was done. Sitting next to the stock mount: 929 shock and new mount: Zach571

Gotcha - someone come up with the dimensions and I'll make a couple of them. I could use some final dimensions as well for what works for the 5th gen. Either the specs of your mount, our the difference between your mount and the factory mount. Seems the R and D has been done already and I won't be able to try out different lengths till April at the very earliest. The final length of the 5th gen mounts hasn't really been spelled out too well, yet. Thanks for any help on that. I'll post up when I get some done, but would be easier if I had a dimension to work with :fing02: Zach571 Hey Zach - thought I'd follow up on this...need to get the beast fixed up for an upcoming ride. I know you have a stock bracket in hand, so I am 99% sure you need to add 42mm in height to the existing bracket, and the resulting longer bolt would need to be 110-115mm long, M10 diameter. I called a welder, sent him some pics and mockup...said it would cost $200 to add the spacer, or $150 to just fab a new, longer bracket, like the one you drew. Any chance you can fab one up for me for less than that? Dan B Uh, yea, I should be able to beat $200 no problem, including shipping . 42mm sounds right as well from what I recall reading through this thread. I'm really hoping some of these guys who have had there's in for a while will post up how its working for them and either the new dimensions of their bracket or how much longer their bracket is now. My design, (if it works out, gotta make one up and see how it looks as far as strength goes) will require a new bolt, but will not require it to be any longer than the stock one. Not to mention, shouldn't require any welding, unless there a gusset will be required with that extra length, an inch and 5/8's is how much longer the bracket will need to be. Also, it should be "keyed" with the frame rail as the factory one is. Dan B, pm me on the subject. How soon are you looking for this?? I'm thinking of installing my 929 shock after I can put a couple hundred miles on this spring. That way I have something to compare it too, need to refamiliarize myself with how it handles with the stock one first. Anyways, that boils down to the fact that I may not be the first one to use my bracket :biggrin: Zach571
