Because you specifically mentioned 'rumble', you may never get the sound you're looking for with an equal length header - an equal length header is my preference, but it doesn't provide the Subaru 'rumble' that an unequal length header does. This is something you need to keep in mind.

Changing to an uncatted front pipe will give more power and volume, but again without much more 'rumble'. You will definitely need a re-tune to avoid ECU codes. Out of curiosity, what tuning system are you using to re-flash your ECU?

The Invidia N1 is loud, and with your proposed changes it will be extremely loud. The Q300 is quiet and may keep noise at reasonable levels, but again without much more 'rumble' - are you looking for more power, more volume, or more 'rumble'?
