advice: do NOT use copper Silcone on exhaust
Once upon a time I was advised to "seal the joints of my Brock Hindle with hi temp(copper) silicone"
Seal it did, absolutely no leaks.
However, after more than a year of leakless use, it damn near defeated my attempts to separate the mid pipe from the 2:1.
I'm getting ready to sell the Hindle and the whole system will be hard to ship; finally got it.
What a PITA! NEVER using that shit on an exhaust again.

WOW!! I hope you did not use a Gallon of it  in my case, the stuff turns to a sort of Powder and actually helped me get my system apart. I have heard that others use Anti-Seize and had no problems either way.
ALl I have ever done is tap the parts with a rubber mallet and as I tapped they came apart. I had a previous system that I used nothing on and I "Swear" I will never do that again either because the system welded itself together

My Brock SW got WD40 to get the pieces together and that's all it gonna get .
The fit is so close, I really don't think that anything is needed to "seal" the joints..

Vincent,
I can see using a hi temp moly grease, but the silicone sure didn't work for me.
Perhaps I put too much on or too little, who knows???
I did get a powdery substance from the burnt copper silicone, but in my case it locked the pieces together.
BTW: how is yr nitrous development going?? Are you gonna make it to Maxton before the snow falls?
Or... Forget Maxton, time for a road trip.
Texas Mile is Oct 22,23, and that track sure isn't gonna be throwing chunks!

I never leave anything together that long. If you're not taking the pipe off froim time to time for nothing more than just cleaning the engine than you're not talking care of your shit and it's not running at it's best. Anything in a high state of tune needs to be cleaned just like your own ASS!!!!!!!! After every use!!!!!!!!!!!!!!!!!!!!

gunner,
I change my motors pretty regularly, but why dismantle the exh system every time???
It comes off the bike in one piece, goes back on in one piece. MUCH faster than breaking it into components. The silicone st up immediately upon the first very hot operation, so why would i treat it like my own ass??? huh???

Figure of speach only. I have been down all these roads and already know what will happen if you glue it together. Now you know and everyone else reading this. I know several of you guys drag race your 12 and that's cool. In your many travels have you ever had the pleasure of meeting Bill Hahn Sr? Bill is the smartest man you or I could ever have the pleasure of knowing. He's all knowledgeable and cuts thru the shit in rapid order. I'm proud to say that I spent a lot of time with Bill in days gone by. The point to this story is this he always stressed maintenance. The first rule of that is PM preventive maintenance. In order to set up a PM schedule you must first know everything there is to know about what you're working on. The best way I have found is to disassemble and inspect regular. These inspections reveil failing parts before they fail and either kill you or cost 100 times more to repair. I also have been a part of an NHRA ProStock Car team for several years. These cars are also inspected and cleaned after every use. Like I said anything in a high state of tune needs this. As a personal rule I clean my ARSE after every use, and if I didn't it might just fail to serve me one fine day when I need it most. This isn't intended to make anyone mad or cause hard feelings between you and I. I respect you and your knowledge of the 12. It's simply ment to point out to some of the guys whom are learning that when they are in doubt clean and inspect. You just can't do a thing like that too often. Kinda like one's Arse....
It's all good!!! and we're all friends and family here RIGHT?

By the way I use Anti Seize on my pipes. They're just too thin walled to beat on with a dead blow hammer to get them apart.

The Copper "Almost" got me because I had to take the Megaphone off and send it back to Hindle and I had only run it a few times. Now that had me scared! The only real problem for me is to avoid pointing the pipe at anything while it is blowing the hot silicone out for the first time. This is also the problem I would think with the Anti Seize but the difference being it never dries.
Gunner A Dead Blow has more force than the Rubber Mallet (touch & feel )

If you have to "seal" it up, what does that say about the pipe?
I'm on my second Akrapovic - for a reason (not money and not brand loyalty).

Blitz I have an Akra on my second bike and it's a nice pipe, but it's no Arata for sure. Looks nice and all, but has a small hole in the back. Fairly quiet as well at low RPM seems to rev clean. I haven't had a chance to road test it yet. I just finished the bike tonight. OH and didn't you say once about a time that you didn't have a PC on your bike? I took the one off of this bike. It was so fat I don't see how it ran. I sprayed the exhaust ports everyday for a week with Deep Creep to loosen the buildup and hopefully burn and blow it out now that the PC is history. I think that's what that stuff Mamba sold was for wasn't it. Nitrone or something like that.

gunner,
I agree about Preventative Maintenance; I just wouldn't have put exhaust system joints on a list of items to address.

I pretty much gave up on the mid pipe of my Muzzy Ti seperating from the header.
The Akra SS comes apart just fine though.

Actually I wouldn't think of it as a problem area either. On my Ti pipe I use Anti Seize just because Ti like to gaul so bad. Little lesson I learned from George Bryce about 20 years ago when I was using Ti axles and nuts  . Also if it leaks a small amount around the joint it don't matter. If it was one of my turbo bike than it would matter. By the way owning several turbo bikes thru the years has conditioned me to watch my header pipes closely. It just carries over to all the pipes even the no turbo stuff.
Sometimes I don't think I enjoy my motorcycles as much as some of these guys that just ride them and never give them a second look. Mine do spend a lot of time under the microscope being maintenanced. Any motorcycle that performs like a ZX12 does needs constant attention and shouldn't be owned by people who couldn't keep rust off an ANVIL.
Back to your original post Sir thank you for the warning. It has been noted

this topic is bringing back a memory I have of the pipes I had on my Ducati 900ss... I switched the mid pipes out to make them high-slung... road the bike down to the post office, picked up the midpipes and had to send the old midpipes back... (anyone who's had this bike knows its a breeze to work on).. so I figured I'd just swap the pipes right there at the PO and stick the old ones in the mail... well I'll be if the stinking pipes werent seized together, and after only 6 months of use.. could get 'em to budge... a guy on a harley lowrider stopped and rode me back to his house where he had a full shop and we pulled the bike apart after heating cooling and restling with the pipes for about an hour....\\they shoulda just come apart... 5 minute job became an afternoon,

Blitz if the fit had been loose I would not have been worried. the problem is the fit is just short of a Press fit and I wanted something in there to make sure they did not WELD together specially like TI Pipes do! BTW, I first used this on my Akra system

Now you done it Vince! You have alledgedly slammed the legendary Akra system. Bad things will befall you. Probably alot of crazy shit like all your header springs will become sprung. hahaha

Agreed! and until ARATA came out, I would have also agreed that no pipe had better build quality than the Akra (Serious hand welds as opposed to the more "industrial" look of my favorite pipe)
