I bought a £150 beowulf can which does a cracking job, but there's plenty of others available: scorpion, blue flame, carbon can companyto name a few
and further to an end can, there are full systems available which I'd have thought would do away with any cat's full stop

No not for the Track..

I had a FZ6 before and could wheelie it all day... SV not a hope!
So tuning it!!

Teka tuning the ECU
De-Cat along with Carbon Fibre Scorpion Street Extreme
Pipercross Filter (K&N is too restrictive still)
TRE

If that wire meshy thing comes out with a screwdriver does that mean no cat is in there????
Whats the point of that mesh!!!

Well I'm not a mechanic or anything but I'd have thought the mesh was there to mess with gas flow before going into the cat or summink?

Also, have you looked into the oil starvation issues which come with wheelie-ing sv's? I've only ever heard it mentioned but it seems quite a common thing

Then with respect your technique is wrong. I could wheelie my completely standard apart from an end can SV with no trouble at all.

TBH you'd get more benefit wheelie wise by altering the gearing than you will chasing power gains IMHO.

My K6 had the corrugated material and no CAT so I pretty sure its for sound deadening. The actual CAT should be well buried inside the can but changing the can wont affect the O2 sensor in the collector or the injection system.

I thought the corrugated material was the cat? i thought the can was used just for sound deadening, especially considering how big it is!!

no CAts are made of platinum or something equally expensive so wherever it is it's going to be bloody small. I think thats how they sneak it in the can with no one noticin!

De-Catting for wheelies .... heard it all now , you wanna pop the front end up then travel at 30 in second , slam the throttle shut then whack it open again , that will lift the front end up on a bit of private ground . Oil Starvation can occur , knackered head stock bearing will probably be eventual if you land a bit heavy too , then again you did them on the other bike so you know the drill . Sprocket size would be easiest option in the long run , welcome to the site by the way .
