as title what sort of cat does my 2008 R1 require for emissions?

is a standard 200 cell like this one fine? UNIVERSAL PERFORMANCE CAT CATALYST CATALYTIC CONVERTER on eBay (end time 09-Feb-11 11:47:49 GMT)

i will be welding some sleeves onto it to make it easy to remove, so it doesnt permanatly steal power.


cheers

i used one similar to that on my 06 R1, it worked just fine . I had to really lean out the mixture too to pass the emissions test. but thats really easy with the power commander

You should be OK with that. 400cpi is standard, 200 is performance cat and will work OK, giving better flow. There are some 100cpi high flow ones but they're a bit marginal for the test.

thanks, i will go with this then.
