Hi All,

I want to make my M5 sing. As my car doesn't have particulate filters, can I get some advice on the best option.

Option 1:
Just an audio boost to rival the E63s

I was considering a remus rear section and then read on here that deleteting the resonator ia also a good option.

Does deleting the resonator create drone?

Is deleting the resonator equivalent in volume to a new back section from the links of remus?


Option 2:
Unlocking performance without the smell of fuel/petrol.
This is very temtping especially if I do a tune, buts its the family car so the smell of fuel is a no go.


Can high flow cats deliver the same or similar results as downpipes?
These seem decent but they make no power claims which I found strange:

What is the best bang for buck for this option?


I plan on doing other mods so I want to save cash where I can, including:
- Lowering springs (MSS where recommended by Evolution e but they cost £900 fitted)
- CF lower trim pieces and grills (some on ebay I heard are decent quality and fitment if anyone can confirm
- Wheels
- Small bass upgrade to B&W system.
- Tune (I am very tempted but worried about the engine going pop).

Thank you all for taking the time to read and help me out. Very excited.
