hey guys just need some help. I got a new 2.5 inch exhaust system and extractors from a friend and i was just wondering if you need to run a cat on it being a 86 model.

thanks harry

My '87 has been through two RWC without one, but a fitter told me it's quite a big fine if caught in roadside check.

Ok so would it be worth putting one on incase

Technically an 86 model petrol 4wd isn't required to run a cat conv. but seeing as everyone now uses unleaded fuel I think every petrol vehicle should have a cat fitted.

Ok so I don't NEED one I should just have one on.
The system has a cat but its straight off the back
of the Extractors and the cat hits the chassis rail
So that's why I wanted to know if I had to have one

if it runs as bad as most carby g13's a cat would be stuffed in about 10mins flat un burnt fuel will kill their coating

Myn is a g13b and it runs pretty good with the 2.5 inch system

so you're running a GTI motor? If you are you need to legally run a cat.
