I bought a a cat. Then I got my SVA (carbed R1) I'll never have another emissions test so the cat's come off for someone else to use. The plan is you buy it, use it, then either keep it or sell it on again ;^)
It cost me £145. I want £100 + postage
It's been modified to be easy to use with an R1 titanium can.
below is a picture of the cat - you can see it is SVA radius friendly & my MAC certificate says it does the job. Here's a link to a picture of it on my car.

The tubes on the cat are a tight fit in the titanium pipe going into the R1 can - a s/s clamp on this seals it up. They are also slightly angled to take the exhaust round the slight bend in the side of a locost.
My car now has this replaced by a short length of 2.25" stainless tube.
u2u me if yr interested

for a second there I thought that was a pussy cat you were flogging...

How sure are you that you won't need to do another emissions test, say at MOT?

The car's on a Q & there's no emissions data on the V5. I checked at the garage where the MOT would be performed & after some delving he confirmed it's visible smoke only (ie not even 300/1200 non-cat test!)
excellent!!!
