I wanna make my 2011 crz a little louder. Not loud in like an annoying sense but just enough for it to have a little growl when drive so I can hear the engine. Any ideas. Sorry if it’s a confusing question

Try a Short ram intake.

Do you want intake noise or exhaust?

If intake noise, i think you can do a resonator delete.
See: What is purpose of intake "resonator"?

If exhaust, buy a quality muffler and (depending on state) remove the 2nd cat.
