Carwing they call differently in different country ! the back box or the muffler on his own will not gain the power isn't ??? full system will (depend on design some gain BHP some gain LB but since 94 0r 95 in uk you have to have CAT so a lot of people take the CAT out(replace with a strange though pipe) for time being ( put it back on for car test MOT) or expensive way is buy the after market CAT replacement (called sport CAT) !
BTW i think is pointless just change the back box(par from look better) always go for full system ! |
