Gonna be going for a resonated cat back (I think, it's a daily drive and i don't want cabin drone?) but I wanted some tailpipe advice?
I don't know what sizes are too loud, what's too quiet? Seen a nice 4" inward rolled but is that too small? It's all hurting my head lol, want it to sound like a scooby but not crazy if you get me?

 

Im a big fan of the prodrive rear silencer, gives a nice burble not very loud and looks the nicest design imo.
