I think general consensus is:
- front resonator by itself barely worth doing
- both resonators + x-pipe (or h) is a modest increase - many people seem reasonably happy with this, and no emissions/smog worries
- secondary cat removal best bang for buck, particularly when paired with dual resonator removal + x-pipe (or h). You can also leave rear resonator to take advantage of the x built into that resonator
None of those options seems to give drone, and when engine is in comfort with valves closed it's still pretty quiet.
I would like to do secondary plus resonator removal. Finding a shop in Cali to do it that isn't a complete hack job is challenging. Thinking of either buying the PSI one and and installing myself (expensive) or doing dual resonators and telling myself to not be greedy
