Congrats on the purchase, I'd highly recommend an Eventuri plenum and primary cat delete for a wall of sound, you get much more of the V8 experience at much lower speeds with pretty much no downsides, there's no drone.
Unless you're on it, it sounds almost stock, you'd have to lose the cold start for the sake of your neighbors though.
Once you hear it, you'll find yourself a few €k lighter, if you're anywhere near Cork, you're welcome to have a listen to mine.
