You can also add an intercooler, charge pipe, and catted downpipe. I doubt they would ever notice these mods.

Just don't upgrade the exhaust
so a valvetronic dual exhaust and rear diffuser swap wouldn't be a good idea? closed valves and taking off cold start shouldn't be too loud right? just enough to tune burbles when i'm on the road

if that's not a good idea, what's your opinion on getting an upgraded intake and inlet pipe solely for the sound?

ty for the recs
