Hi Guys,

I'm not sure if this is a really stupid question, or one that has been answered before, but does anyone know if changing the dual pipe backbox on a Metal (or a 134 S1600) to..say a single pipe Powerflow 3" backbox, would result in any sort of power loss?

thanks!

If anything mate it should give you a power gain, as the powerflow is classed as a "sports exhaust" so the baffles and what not will be mostly took out
