Exhaust mounts

[ankhtat]

Many custom pipes don't come with brackets cause there are too many models of bikes out there. So you need to make one with some 1/4 plate strap steel. Don't let them hang like you are or they will break off your exhaust studs. Believe me I know.

not to sounds completely retarded but I fear its inevitable ... do you have any instructions on how to make a mounting bracket, tools to use etc... I figure i'll need an L-shape piece of metal and attach that to a straight piece of metal and call it good BUT the stock brackets had like rubber grommets etc.. not sure if anyone knew the proper way to make one.

First question is where is the mounts on the pipe? Are they disigned for transmission mounting or frame.
If it's frame then you need the plate and a torch and a vice. Heat up the plate and bend it in the vice. Then measure and bend again. Drill your holes and your done. For transmission mount it's a different animal.

the two mounts on the back of the pipes are right near the tips (hard to see in the pics) I have a single 5/16 bolt through them which is keeping them gapped perfectly. but it sounds like i'll do just as i thought.. I'll use the stock l-bracket off the frame.. attach another l-bracket i make.. and then attach just one final straight piece to the new l-bracket...

lol sorry if that little diagram looks funny.. I should try drawing it on paint (YAY).

but no grommets for vibration issues or anything?

I get pieces of aluminum from Home Depot to make my I brackets to hold the exhaust to the frame. It looks better IMO.

Well i was never happy with the way my V&H BR's were mounted from the dealer that installed them so I made a bracket last winter out of a piece of 1/2" aluminum.

The bracket that was on the bike let them "in my opinion" they stuck out too far from the bike causing them to drag on low right turns. and the gap between the pipes was never even.

So i started with a 1/2" piece of wood and made 2 prototypes first. playing with bolt hole locations . got one that i liked and transferred it to the aluminum piece. Drilled some holes in it to mach the forward controls and polished it up...

Nice and tight to the bike..

test fit..

Done

Pretty neat job there,N8KAM:

 

[Mickeetwo]

That looks nice Kam....good work :2thumbs:

that is a very neat job but I do have a question and probably a very dumb one but here goes:

how can you change the angle of the exhaust (how close it is to the frame) with the bracket. Is the angle of the exhaust not set when properly torqued to the head so that you then need to make your bracket fit to that?

so freakin tired... I will post pics once finished .. but here goes...

My buddy and I picked up a 1 1/2" w x 1/4" d x 36 " l bar from home depot.

We cut 10.5" off, basically, we are going to mount this new bracket right on the frame where the stock bracket was. We then made our first bend (after several long minutes of heating and some hammering) at the 3 in mark.. not that easy to bend this stuff, need that pipe bending tool from occ lol.

We then checked the angles (we were shooting for a 60 degree but ended up with closer to an 80 degree .. which is fine (why we gave ourselves 10.5" when we measured off around 9.5).

Next bend for the part to mount onto the pipe... we measured out 3.5" .. heated it up .. going for a 100 degree bend (since we got 80 and not 120). We got the bend we wanted, let it cool for a minute.. checked the part next to the bike.. realized that the bend started at 3" not 3.5"... big gap now.

It got so f*n late that we called it a day, and will resume tonight.

I bought some hi-temp ceramic aluminum color paint for this bracket... wasn't sure what to use and figured crome paint wouldn't stand up to those heated pipes very well (probably went overkill with hi-temp paint).


This saturday... wrapping the pipes project. picked up some DEI hi-temp silicone black spray to help maintain the wrap when finished.

Quick question, what should I wrap and where .. my thought was on the front pipe, wrap around the lowest right before the final bend for the arc'ing tip (i'll attach pics of my pipes again).

For the back pipe, I was thinking I would wrap down to the top of the very first bend. This should leave about a ft of chrome on each pipe. I marked the points on the pic in the attachment. The problem is the overlay between the top and bottom pipe when they cross.. well there is a mm to nothing gap there (seriously touching) so I doubt I'll fit wrap between them.

Don't mind the lame attempts with ms paint

I have a thread on here somewhere showing how I wrap my pipes. Probably in the exhaust section. Even have a vid showing the first start and all the smoke from burning them in (painted). I used the DEI stuff too, it's pretty good.
Just remember that if you are using clamps at the top of the pipes give yourself enough room to work with the flanges so you will be able to get a wrench in there when it's time to install them.

I was actually thinking about starting the wrap right were it progresses from like a 1 3/4" pipe to the 2 3/4" pipe (so right at the starting part of the larger diameter pipe).

I've gotten some great instructions on wrapping from various sites... the only thing missing was whether or not I needed to cure the wrap (start the engine etc) before I applied silicone spray?

That should be good just make sure that your clamp (if you are using radiator clamps) are situated so that your 1/2" socket will fit the stud.
I tried to find my post on wrapping but couldn't and I need to get out of here but quickly. I soaked the wrap in warm water. Tied it off to the water faucet on the side of the house then stretched it out and started my first wrap on the pipe. While pulling or applying tension on the wrap rotate the pipes and try to achieve a nice overlap of whatever it calls for in the instructions. Easy to unwrap and do again if you have to but hooking the other end to something really helps. Oh, wear gloves cause that has fiberglass in it and it will get in your skin. I painted mine black when I was done. Vid in the BDB vids under the General section I think.

Have fun,

issues with vibration?

when building a mounting bracket, is it ok to mount it to the frame and pipe direct or do you use like rubber washers to absorb vibration to prevent breaks or anything?

Well Lee. I had just had the heads redone so i had New exhaust gaskets for one... I removed the original bracket and the pipes were able to move closer to the frame without needing to put excess strain on them... after the bracket was installed i rechecked the torque at the heads. and have had no leaks..

Also the bracket that was on it according to V&H was for a softail Harley, and probably made it stick out to far. here is a pic of the way it was when i got it.

thanks kam

 

[ankhtat]

Finished

Mounting bracket... 9" approx, 2 bends... 1/4" plate steel... hi-temp ceramic paint (aluminum) ... wasn't sure if buying a chrome paint would be safe due to the heat transfer from the pipes.. better safe than sorry i guess.

Thanks for all your help guys

Tonight I will wrap them and post some pics, any suggestions on wrapping in terms of where on the pipes to end?

You can mount the pipes directly to the frame without rubber bushings.
