decat with standard backbox

[demps23]

would having a decat pipe with the standard backbox make the car any louder than it already is? cause I wouldnt mind getting a decat pipe but dont really want any extra noise :S

cheers for any help!

hardly tbh, i ran my cup like this for a year and a half, hardly noticable

 

[demps23]

is that just when you boot it up? or on idle aswell?

 

[demps23]

forgot to say its a 172 cup just incase that makes a difference

hardly anything tbh. Its a worth while mod to the 172, as the cat is restrictive!!! Do it, bet you can't even tell with the noise
