Deceleration pops on VROD engines with straight /baffled pipes.
So after spending more than I wanted to on trying to get rid of deceleration pops on a VRSCDX with tuners and auto tuners heres a $20 solution that works.
Create a Disc of 85mm outer dia and 31mm inner dia and attach it to your pipes this increases the back pressure and makes the engine much more smoother.
