Welcome!
I have a 96 Civic Ex. When you added the I/H/E, does the extra "noise" make it into the cabin? I haven't done it yet b/c I drive long distance sometimes and I don't want the constant drone. Anyway, back to your inquiry, just do what you like but keep it simple. Pretty much everyone here likes clean simple looks. Did you want to work on the engine more or the exterior/ interior more? Either way it's up to you and have fun tuning. Do you have any pics? Welcome again noob!
