OFH + ISIS OP + Stock FP + Greddy Supreme SP CB
 

Recently I just removed my Nameless Resonated OP+FP due to the noise level but there was almost NO drone at cruising speed 3-4k rpm with the setup THEN I installed a ISIS OP + a Stock FP. Noise level has gone down but drone is killing me. What should I do?

I can buy a P&L Catted FP from a local guy and try it out but I'm not sure it will help with the drone since it is not resonated but high flow cat.

Or get a HKS double resonated FP? It will help the drone for sure but not sure about the noise level for being Catless.

Or just I can buy that P&L Catted FP and add a custom Resonator? I'm getting the P&L Catted FP for only $150.

I want to keep the budget under $300 for this.

Any suggestion?
