powerflow exhuast
 

Hi all am thinking of treating my silvia to a new exhuast system and have been advised to go custom, so i was just wondering roughly how much this will cost has anyone got any idea? cheers phil

I think you're looking between £300- £400 for a single box system depending on your choice of backbox.

i paid £330 for a 2 1/2" stainless steel exhaust with cherry bomb center box and back box:)
