Same port, smaller air space = higher tuning...no way around it.
hmmm... but to the OP that should work, just be sure to secure it properly together.Sealed i would just lose some air space which I'm not really worried about I'm at 1.6 ish before displacement so 1.35 or 1.4 would be doable
agree. i was just explaining the effect. id still try to stay within manufacturers specs if possible. but should work, just use some cawk... i mean caulk and screws lolhmmm... but to the OP that should work, just be sure to secure it properly together.
