Hi guys,
So obviously I'm still a newb so excuse the niiave questions but I want to upgrade the exhaust system and still want to pass mot so what can I replace and what should I leave alone?
It already has an afterburner rear section, and from what I've read changing the downpipe to something like a ninja high flow cat downpipe is still an mot pass but useful.
So that leaves first cat from downpipe and centre section.
Which is best to de-cat and yet still pass mot or isn't this poss?
My thinking is leaving one cat on so mot tester can still see a cat etc.
Thoughts and feedback most welcome
