PFL - Catless DP and Res Delete

[Magan]

Hi All, as per above, has anyone done a catless DP and Res delete on the ir PFL RS3. Interested to know what it sounds like with valves opened and closed and if there is any drone? TIA.

Forgot to mention, looking for reviews with those that have the RS sports exhaust in conjunction with Catless DP and Res delete.
