Mountune Exhaust Comparison- Catback vs Sport CAT Downpipe and Catback (Turboback)

Sound comparison of a 3 gear pull of a 2014 Focus ST fitted with the Mountune MP275 Performance Package, stock downpipe and Catback Exhaust versus the Mountune Stage 3 Clubsport fitted with the Sport CAT Down Pipe and Catback Exhaust.

Definately sounds better without the sports cat which will preclude having the MR300 upgrade. Got the cat back on my MP275. No booming or droning inside. Definately sounds throatier and sportier than the standard.

This is like 2 years old now xD. How much did the interior noise increase after the downpipe?

I have the MP275 upgrade and im close to purchasing the exhaust, but I cannot figure out if its worth getting the sports cat also.
