Ok. Getting ready to cut these cans. Anyone have any advice on what to use?
I'd use a cut off wheel.
don't burn your house down, ti shavings supposedly catch fire in certain circumstances
Personally, I'd use a bandsaw.
dremel and a few beers to keep your hand steady
use a wet tile saw.
the water will keep the Ti from coloring when the cutting heats it up.

Good idea if you have one.

If you've ever tried it you must have had a really good blade.
+1 cutwheel would be fine. if the ti gets too hot it'll discolor. it's magnesium that'll burn your house down if ignited.
I used a chop saw on mine. took a good bit of pressure to cut through it, and it produced some really cool looking white sparks.

Most people don't realize that Titanium is a combustible metal, but it is. Look up titanium fire and see what turns up.
Aluminum dust is also an explosive solid.

that's why the hindenburg burned so well.

the titanium would have to reach 500º+ to become a hazard. grinding in an area where the shaving wouldn't collect would keep you safe.
You don't happen to live in San Fran and began cutting around 6pm last night did you?
i want to laugh at that. (but am going to try to refrain)
May be a toe over the line. In all seriousness, I hope that situation is taken care of ASAP and RIP to those that perished.
Back to the subject: How'd the cutting go? I can't wait to see the final outcome so I can decide if I want to cut mine down or not (CF not Ti though).
Still haven't cut. Trying to get a hold of the proper tools. Think the chop saw is going to work best. Hopefully this wkd it'll get tackled.

Cutting carbon fiber has it's own issues, with the largest being the dust. The carbon fibers are VERY bad for you if they are inhaled. The best option would be to cut it wet and wear a respirator.

Thanks for the reminder [thumbsup]
I just put my Arrows on Sunday and I actually don't mind the length, so I don't think I'll cut them now.
Just received the rivets for this project so should be this weekend. However, I know that I should cut the Ti with a wet saw, should I drill the new holes in any special way as well? Thanks.
NM...went by the machine shop that is cutting the mufflers themselves and they said they'd take care of it! Sweet...hopefully done by Saturday evening! Now to get before and after videos, if only it would stop raining here!
I like my exhaust a lot better since I shortened the cans. If I remember right, I cut about 4-4 1/2 " off. Most aftermarket exhaust looks way too long if you have a tail chop IMO.
here are my remus Ti with 6" cut off. Used a cut off wheel, nice white sparks, no discoloration.

Edit: cut off 6 inches. Same as tail during chop.
Well dropped off the cans today to get cut. Took me about 30 minutes last night to get the rivets out and another 3 hours to get the endcaps off!!! What a PITA. Should have them back today and back together this evening. I already took a before video, and soon I'll have an after video and pics up.
Ok guys...get the cans back together and mounted on the bike but the thing misfired on me in a turn and ALMOST put me down. The bike was towed this morning to the dealer and stupid me forgot to take a pic or video. Hopefully it won't be too long. First impressions: looks much more proportional to the bike, NO noticeable sound difference. These are both good things to me.
Glad you are ok. In what way did it misfire?
The misfire is always a cough through the airbox for me and no power. Not sure what caused it but as soon as I made it through the turn and continued home going straight it did it again, maybe 30 seconds later. I've been living with occasional misfires but after this one, not tolerating it. The bike has a damn Nemesis on it for god's sake. Dealer better fix this crap.
cam timing should be inspected.
I cut 6 inches out of my Arrow ti's and it backfires around 4k the same as you described. I have a custom mapped PCIII and just assumed it is running lean at mid range. I added a little more fuel at 4k because it only happens at pretty much that exact RPM. I haven't ridden it to est it out.
IM making a Ti exhaust and i have found the best way to cut it is a chop saw with a carbide tipped blade. Band saws suck in general for Ti. You may need to clean up the cuts afterward with a carbide burr on a die grinder. I realize your are already cut but im putting this out there for future refrence.
Sorry for no update guys. Got the bike back and it is still doing this crap. My dealer said the insulation was pushing on the ECU connections and that could have been it so it was removed but it still persists. Was riding last night and it did it two different times once around 3250 rpm and once around 3750 both about 10% throttle. However, from the retuning, the bike is supposedly making more power.
Alright...here is the finished product:

I'll put a video up on youtube shortly but the difference in sound isn't as drastic as I thought it was going to be which is good for me at least. However, the bike did make ~3 more hp and corresponding torque on the dyno being retuned. Interesting little bonus.
same dyno as previously tested on?
Yup...same dyno.
what is that, like 1hp per inch of pipe removed?
;D
