Resonator delete question

[CD_N54]

Hi guys. Not to start up another exhaust thread but I couldn't find anything on this topic here. I am installing a 135i muffler and doing a resonator delete on my 128i as it seems to be a popular combo for these cars. I live in CA so the exhaust laws suck here. I was just curious as to how loud this mod is gonna be. I couldn't find any concrete answers. I'm still keeping the stock headers and the cats. It's only a resonator delete. Just wanna make my car audibly engaging to drive without being too loud and drawing attention from police. Thank you in advance

Also bonus questions. Has anyone had any significant back pressure issues with this mod? It's another thing I was worrying about

I had the Performance exhaust on my old 135i with Y-pipe (resonator delete). It sounded louder but wasn't obnoxiously loud. Like you, I also live in the Inland Empire and was never stopped by the law for sounding too loud in the many years I had the car. This is not an exact comparison but it is similar because of the resonator delete.
