Can stubbying questions

[dirtydog]

Right i'm just about stubby my akrapovic can cos it's absolutely mahoosive and i want to turn the inlet cap round cos it's damaged

Am i going to have a nightmare cutting the titanium sleave?
Do i just use normal pop rivets to put it back together?
How short should i go, the can at the moment is 600mm from inlet to outlet?

you want to cut a beautiful akropovic exhaust?! :eek::confused: how about i swap you for my fuel one and you can stubby that instead? ;)

I'd chop it to about eight inches

I've used those folks, decent enough.

Titanium shouldn't be too bad, rivets may give you some galvanic reaction, but I'd use stainless and see what happens. Or figure out what the originals are.

Unfortunately i dont think that a fuel can will fit my akrapovic system plus the akra can is massive!!!! That and the fact my akra can cost a whopping ?300!!!!!

Well the rivets drilled out bloody easily

If it's not too late I would cut it 2/3 : 1/3 then you have a choice how to build it back up (& could even cut again to get 1/2)

[yorkie_chris]

Possibly Ti rivets?

Find a chunk of one and take an angle grinder to it and see what colour sparks you get.

Wont be attacking it till tomorrow, if i go with 2/3 length that takes the total length (from end of inlet to end of oulet) to 460mm compared to the 600mm it is now which looks about right to me

What colour will the sparks be for Ti and SS rivets?

[yorkie_chris]

Ti sparks white, SS short sparks and more like tool steel. (depending on alloy, still an easy comparison though)

Sparky sliders i've seen have been orange what would they be then?

[yorkie_chris]

Maybe a type of steel, maybe the road going past slower and being smooth doesn't generate as much heat, maybe the melted plastic changes the colour.
Basically I've no idea.

Proper Ti makes white sparks, it's totally different to steel.

Cool i'll take my grinder to a bit tomorrow

they seem to be SS rivets

[yorkie_chris]

Makes sense, ally rivets never last long, and Ti ones are probably a fortune!

[dirtydog]

Hmmm how strange, i've cut the sleeve and the inner perferated tube down and put it back together just to check the size it now is and thought that i'd wrap the rivet band back found it and the holes now don't line up properly????? :confused::confused::confused::confused:

[Stu]

You've got them mixed up or upside down?

[dirtydog]

The one from the frontt of the can has got a chunk missing out of it so i know they aren't mixed up that way but it doesn't seem to matter which way round i put the rivet straps not all the holes line up!!!!!

[dirtydog]

oh and i've cut about 170mm off the length of the can, need to neaten up the cut end a little bit. I have ordered some new packing and rivets so hopefully will be all done in the next few days

[Stu]

So can you make up a 170mm stubby? (as well)
