What are you running for muff mate ? Put a set of open ended cones , no baffles aim for about 4 inch end for a start . It will give you a negative pressure at the end of the headder and it will be like 165 Db loud (very) If that gives you the top end you want then you add reversion cones on the ends to bounce back waves just like a two stroke for mid range .

Yeah legend I’ll run the 1 7/8 from about 3” from the head from the 1 3/4, when the 1 7/8 does to a 45d heading out back I’ll go 2” or 2 1/4 for around 100/120mm - you’re right on the money 💰
