Have been contemplating adding a decat next to the centre section and leaving the cat in on the downpipe, I already have a ninja backbox and afterburner centre section, how much louder will the decat make it? Will the light come on on the dashboard?? I've been looking at scorpion because its cheaper than the afterburner any other ideas?

 

Got a classic decat center pipe but has silencer in it that looks like decat £35 delivered

 

Straight pipe all the way

 

No it shouldn't put a light up, only the first cat that may do that, due to the sensors present. I have a full turbo back system and it wasn't that loud. Only when I changed the system to a blitz it got its bark. I would say the backbox choice is the key to most of the noise.

 

I do want it louder, but can't afford a new back box at the mo although I have contemplated a race pipe, do you think the scorpion will math up ok with the afterburner centre?
