How to not lose power at low rpm plus reduce noise at low RPM. Hey, can you confirm how it reduces the noise? Why only at low rpm? I assume this is for de-cat systems only? Apologies for all the questions.

Modded link pipe instead of oem breadbox , there are no cats inside , noise reduction due the oem looklike exup valve .

looks very good, I think exup system really looks after the noise levels without touching too much of the power delivery. And I am still quite sure I will create some BackPressure which will beneficial at low revs. Can you still able to fit the cover on top of it? The only thing with Graves EVR system I cant fit the cover on the Exup unit which cables are open for road debris
