Prodrive back box
 

I currently have a deresonated centre section and sti genome rear silencer on my my05 jdm sti, I am considering a quieter backbox, does anyone know if a prodrive backbox sounds any good on a twin scroll, and before anyone asks I am not selling the genome I just want to try something out, I may settle for a resonated centre with my genome but not sure how much difference it would make. Anyone experience of a genome with and without centre box.

Had twin Genomes on my BL Leggy and they where fab. Fitted standard Subaru stuff and it was sooooo quiet.
