Right guys very new to the 350z and also decatting. I've never had a decat exhaust before, purely because I've never really owned a car worth doing it to! Picked up a scorpion exhaust system yesterday and fitted it, sounds nice! But I still want that more of a grunty rasp which I've heard can be achieved! My only concern is the whole management light coming on. Yes I have a friendly MOT tester, but I don't really want the light on the dashboard to be fair. I've had a read up on 02 spacers, are these actually any good? Do they really work? Will they stop any lights coming up? Or will I still have a hefty bill to foot when I want the light turned off? Any insight would be great guys! Cheers!
