Quiet HP Increase in Exhaust

[The Radium King]

i think that the further you get the cats downstream, the better the exhaust airflow is able to setup and, presumably, add a bit of power. so, some catless headers, and relocate the post-cat o2 sensors to after the secondary cats on the midpipes.

otherwise, 987 exhaust has a better sound and will make more power. apparently it bolts right up.

I’ve read this in multiple places before. I can’t seem to recall anyone having actually used the entire 987 setup to confirm yet. I’d try myself, but it’s hard to find an entire setup in canada for a decent price just to experiment with it.
