Gotta straight through system to prodrive bbox, happy with the system but looking to get rid of the 70mph drone and not sure whether to replace the centre section for a cobra or H+S resonated one or just have a silencer put into the existing centre?

I also have a Prodrive exhaust and removed the center silencer for a straight pipe, after only 2 weeks I'm putting the middle silencer back on, the middle straight pipe didn't improve the sound and created drone at 70-90 mph.

I'm not wanting to put the original section on I should have added, would be going for a stainless option

I used to have this centre section with a ppp backbox:

Measured 83db on track days, and as I recall, it didn't drone either
