Hi, I have read extensively on how to core the pipes on my s4r but need a chop saw to get the job done.  If you live in S.F. and wouldn't mind me using the shop saw for oh about 15 min I'd really appreciate it.  Thanks

I would go to the nearest home depot and buy me a chop saw and just return it after you use it..

 [thumbsup]

good idea, but only have the bike, so might be a little hard to ride it back,  [moto]

Desmostro has been known to help people core pipes...for a fee ;D

I know we talked but I think he wants to actually do the job and I'm short on the cash monies, being a student and all..  I know how to do the core, just need a saw to cut the bread, I can handle the rest.  All in all, if I take the pipes off it should take around 45 min or less.

I don't want, I'm just saying,

That's not a quick job. I looked at the 'how to' posting for those pipes.
(FYI, they way it was done there, those puppies are going to be LOUD.)
That guy took a month, and an extra set of pipes to experiment. Sacrifice in the name of science  [thumbsup]
I don't know if you've ever tried to Dremel your way through stainless steel. It's going to take a couple of hours and a lot of little cut off wheels to get through just the double layered end caps.
It gets easier from there.
It's not rocket science, but it's not a 'crank this out' in a couple of hours job. This is a couple of afternoons to do the whole thing prolly.

You need:
Dremel + cut off wheels.
Angle grinder + cut off wheels.
Drill
Pop rivet gun + Rivets
Hack Saw
Perforated stainless tube or sheet to bend into a tube.
High Temp Silicone sealant
...and some cleverness, because there's no photo's of how to put it back together  [laugh]

Should be loud, but not ridiculous.  I already have the perf tubing, stainless steel ties, and exaust packing, rivet gun and rivets, just need to hack deh pipes.  Should be able to chop them two times each then put tubing in with packing and ties in place, put end cap and sleeve on, drill 4 holes, rivet, seal, donesky

Desmostro, I did the old style 1/3 core on my m750 pipes with a dremel, and it took forrrrrrrrrrrrrrrrrrrever.  I totally agree that way was riduclous and took a long time.  This way seems pretty dang fast and easy.  You have more experience than me with this stuff, but with all the research I've done, I feel like I have a pretty solid handle on what needs to be done and time alloted.  Damn, if I was out of school and working I would have just put a termi shorty on it and called it a day  [thumbsup]

I've done two sets of pipes, one for a Monster and one for my ST2 and didn't spend more than a couple of hours on either set, using a hacksaw - hand powered - and a hand held electric drill.  It was a lot of hard work, but didn't take as long as you're saying.

Maybe half-cored pipes don't take as long?

I found an exhaust shop here in the city where I can get it done, but i thought i would try to do a "how to" video so people could learn how to do this themselves.  Well, we will see how it goes...

I noticed your bike is back up on CL.  What gives?

If you want to come over and use the Dremel - bring the pipes and a pack of "DREMEL thin cut-off wheels" and go for it.
(AND A DENTAL MIRROR so you can look inside)
I'll help you with the angle-grinder parts - that's fast.
You seem pretty confident about what you want to do.


I was going by this "HOW TO" thread for the 696 pipes which seem to be very different than others:

http://www.ducati-upnorth.com/tech/coringsr.php (http://www.ducati-upnorth.com/tech/coringsr.php)

This guys says the only way to get in them is to Dremel cut from the inside of ends of the pipes through 2 layers of stainless blind - as in by fee - hoping you're cutting the right thing.
I haven't looked at them so I don't know if there is another way.

Other pipes you just drill the rivets and you're in.
It's the careful Dremel part that takes for friggen ever. If you could get a hacksaw at it or an angle grinder - you be in, in minutes.
 
I did a simple cat-ectomy only on 848 pipes. It took a couple of hours working fast with no Dremeling, no sealing, no coring, no repacking, no inventing new parts.
That's not including taking off /putting pipes back on the bike etc.

What's on your side here, is that you're taking apart something complicated and making something simple out of it.
It's just going to take some elbo-grease.  ;)

yeah I posted it on CL, well I got the bike for a good deal and if I can "flip" it, why not, I'm in school so no income, but flipping bikes might be a way for me to bring in some sort of monies while I'm in school, we'll see.  After I core the pipes I may not want to let this one go.  I found an exhaust shop that has a chop saw, so I might just cruise by there real quick and see if I can get the chop saw stuff done there.  Basically be just cutting the end cap off between the sleeve and the "D" in Ducati logo on the pipe.  Then once thats off, you can get the outer sleeve off, then cut basically 2/3 of the inners out and then put the inner perforated tube in wrapped with exhaust packer and secured with stainless ties, then just put some sealer over the end cap, put the sleeve back on, drill 4 holes, rivet quick style and yur done.   Well, at least thats what these coring threads have said, I'm going to bring my video camera and detail what happens, then post the results, should be interesting and a quick, easy, and most importantly CHEAP way to get the bike sounding right.
