Hi guys from across the pond

Question please, regarding droning.

I'm looking at getting a spoon N1 Single pipe, could you tell me how badly it drones with:

*testpipe and silencer bung?
*just testpipe in?

I go up a series of hills on my way to work and the droning would do my head as the cars sitting at about 3k - 3.5k rpm up these hills would it drone during these above scenarios???

Loudest after 5k rpm i can handle

Thanks

 

anyone?
