Want to "De-Cat" my K8

Hey Guys,

Been searching all over the net in search of De-cat pipes and the only result has been MiVV Collectors for £125 from brspecialtuning.co.uk

Anyone have these or any other solutions?
How do you deal with the Lamba sensor when putting on a full system?

Im de-catting the bike, whipping in a pipercross filter and getting her teka tuned

Thanks

think the catalytic convertor is actually in the can part of the exhaust system, so an aftermarket can removes the cat and makes it louder/breathe a little easier

i agree with the post above, the cat is in the silencer not the downpipe

Yep...in fact when you cut the stock system to fit the new can and link pipe you can see it in the standard pipe. Get onto the carbon can Co. and order one of their pipes, they are meaty sounding with the baffle in and roar like a lion wthout! Even without mine passed its mot. I dont know if they even have a lambda sensor do they? My '04 doesnt anyway.

i think the k8 has two cats, one in the can and one near the collector, because when i cut my pipe there was the corrugated material just infront of the cut pipe and it was also in the can when i had a look in there. I think if you wanted to totally decat it you would have to get either a full or 3/4 system

Your O2 sensor is attached to your injection so you are going to have to keep that, unless someone has a way round it. To fit it, just cut it back in.

Whitehouse your right..
There is a cat (wire meshy thingey lol) just at the collector.. Never looked in the can though.
Maybe this is only for the K8 i dunno

Forgot to say mate, welcome to the forums

Are you turning it into a track bike? Or just wanting to make it amazingly loud? If you're just after the sound & to free up some gas flow, an end can will do a good job with screwing the emissions etc... 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

When I put the Street Extreme on my K8 I just hacked the corrugated mesh out of the collector with a flat blade screwdriver. It is pretty soft and breaks up easily.
Mine runs ok without it.

When I fitted my can to my sk5, it has corrugated mesh in there as well? Didn't think there was a cat in there as well, since it was louder than the sound of atoms splitting... Hey ho
