Have a 996R. Saw a comment about it needing at least a 54mm system to breath as god or at least the designer intended. However any pointers about which zorst:
1. How big can you go with std headers?
2. Chips and zorst size, any considerations?
3. Noise, how big, how noisy?
For example: if they are to run at less than 102db, is there any diameter limit?4. Are middle baffles any help / hinerance at all?
