Title: Can one "cut" CF Arrow cans?
Post by: RavnMonster on June 15, 2009, 09:47:45 AM
I see a lot of folks with the sortened exhaust cans. It looks awesome. i have the Arrows on my bike and was wondering if its possible to cut these down any? If so how do they come apart? what do i need to know before getting into that job?

i'd imagine they come apart like most any other aftermarket can.

drill out rivets, remove end cap and guts

measure and chop

reinstall and rivet

The most important part is to be extremely careful when cutting the carbon fiber. It will have a tendancy to fray/crack. I would suggest using masking tape. something that does not leave a residue. I wouldn't think you use tin snips or any thing like that. Maybe you could use a cut-off wheel on a dremel.

+1 and keep the speed high and your skin covered. Wera a good dust mask and goggles for your eyes (the king without vents) carbon itches like a mother make the beast with two backser.

Carbon is not the stuff you want getting into your eyes and lungs

if you feel like dropping the coin, a 6000 series respirator from 3M will be even better than a dust mask.

filter pods are replacable, too. hardware stores will have them  [thumbsup]

are the rivets anything special or are they just regular rivets?

It seems to me, although I have Termis and not Arrows, that the Arrows are slightly conical, which means if you chop them too much, the resulting end diameter will end up being smaller than the endcap diameter. The endcaps are meant for the original end diameter of the full-length unchopped cans. Be sure and check that out. I wouldn't know a workaround for that kind of issue.

Here are my shortened arrows; a huge improvement with a tail chop...

Ill measure the diameter first to see if this is the case. i didnt think of that, thanks for the heads up.

my arrows are round  ;)


and I've seen a few ducs (here/TOB) that chopped arrows...


oh, and for the rivets... I'd think stainless would be ok...

S*R shotgun style Arrows look to be slightly conical. It's best to check beforehand. Also, SS rivets are great, but harder to drill back out than AL rivets(in case you need to replace packing). AL rivets incidentally are totally strong enough and cheaper.
