Nice HID conversion - what kit did you get? Hard to fit?
im pretty sure the cat is in the manifold so when you change the manifold it will de-cat it anywaythe kit was easy to fit its all basicly just plug and play i bought them from ebay just search almera HID the kit was 80 quid and a 10er postage bargin. i just found a nice 4-2-1 stainless manifold that ima buy next also a decat as soon as my mot is done.
