The standard Ford exhaust was rotting on my ST and picked up an advisory at MOT so bought a Sportex back box and cat back pipe as it was cheaper than a Ford replacement

BLOODY HELL ITS LOUD

Now I have 2 kit cars that are loud, very loud but the Fiesta is now undrivable without earplugs, I kid you not, there is a drumming resonance that I have to open the windows to reduce.
Came home from work with earplugs in and will be using my sound deafeating ear defenders until I can fix this.
I'm thinking of cutting in another silencer for now but if this does not work what aftermarket cat back systems are usable on the road?
