4.8is Resonator delete?
 

Has anybody done this?

I see that I have cats, center resonator and rear boxes. If I remove the resonator will the car drone on Motorway's etc. Will it be just too loud?

This is a UK Car. When I look underneath I can only see two cats? Is that correct for a UK spec car? I ask as I have an AMG V8 Merc that has four cats (two now deleted).

I am unsure if anybody has played with the exhaust on my X5 before my ownership. It does have a burble and sounds really nice on cold start.
