2- Bore size (mk2 16v/mk3 20vt same bore 55.5mm) whereas as your 1.8 is 50mm iirc so will need a adapter to fit

Just gonna mention that on msn to you, before you went :doh:

The pipe on the cat (going to the centre section) is going to be the standard bore, as flaper mentioned!!! :D
 
don't be bent.......... get rid of it :)






You need to know what bore it is, you may need a sleeve to increase the size to the mk3 system
