At the moment I have a standard system with a tornado backbox from scoobyparts.com its quite loud at the moment,

How much louder will it be if I fit a centre de-cat and sports cat downpipe?

I'm not looking to be quiet enough for trackdays (allthough have a bung for the backbox if i so wish to do them)

 

TOOO LOUD!!!!!

 

VERY, due to the scoob 'rumble' the centre section plays a bigger part in silencing than in most other cars, replacing two nice silencers (cats) will make it very loud indeed!

Please be aware that although it will pass an MOT, decatting means your car no longer complies with construction and use regulations and is therefore (strictly) illegal. (this is not a lecture, as I run decatted centre, just for information)

I'm fitting a sports cat downpipe so should be fine legally? so I should look at at centre section with silencer to keep the noise down a bit?
