Hi looking for information please i had a afterburner vortex rear box which was too loud,i now have a prodrive rear box which is a bit too quiet,was thinking about a ninja box but what will it be like,its for a classic any help gratefully recieved

 

I'm interested in this too. I have the ungodly Blitz Nur Spec R full system and its crazy loud. I bought the bung for it which helped but to be honest I'm just not wanting the volume it produces.

 

Ninja isnt too loud, Cobra is another worth looking at

 

Can't the baffle be taken out of the Prodrive backbox.
