Ph2 cats are a different length, fyi.

Also, make sure you get one with the correct. Amount of lambdas. Either single of double lambda.

Yes but isnt there 2 different types of cats for the phase 1

older models had the twin and newer had single??

i know the ph2 wont fit

right, all ph1's had the twin cat, but very early ones had only 1 lambda sensor. If you have a post cat lambda sensor, then you can use a ph2 cat

You can still use a Ph2 cut just blank the second lambda hole. BUT you'll have to change the exhaust too so no good really.

For those who've never seen a "Double Cat" .. here's mine next to the K-tech Decat pipe.
