I'm new to the forum . I have a confusing in choosing between decat or do both decat and resonator . My preference is to maximum gains after dyno tune and i dont need my bike sound as loud as full system (cops problem).

I tried something similar and it was VERY loud. I ended up having to make baffles where the cat used to be to quiet it up. Depends what can your running at the tip though.
