Hey guys I just installed my Catless downpipes. Have been putting it off for a while. I installed the pipes myself they where so easy to fit. Please note I didn't remove my gearbox and did the whole thing myself in about 3 hours. Everything was to mm precision and there was hardly any adjustment or tuning at all. 10/10

A few posts ago you said the catted version wouldn’t give o2 sensor fault but it looks like the cats are on the lower section of the downpipes so the o2’s would already pickup the out of range readings and set fault code.
