So as I get nearer to fitting my exhaust I've discovered a problem. The engine I'm running is a carbed 1.4 so a NV pre cat engine. The car is a 1993 1.2i so ran a cat. I've had a read in the articles section about when declaring your engine swap you can contact vauxhall to confirm what the new engine came from so to prove it was a carbed model. I've attempted this and they cannot get that info for me due to age!!
I have already got the middle and front pipe from a SR which I was going to fit to a standard 1.3 downpipe and manifold but I'm I best for MOT purposes to fit a standard 1.4 sri system from front to rear box including a CAT?
Any advice would be great.
