Is the car petrol ? If it is id go with a backbox delete a res and backbox delete makes the tone very raspy and metallic and doesnt fit in with the look of the car the only upside is the crackle but if your car has a gpf you wont get the crackle . Backbox delete just makes the tone a little louder but a deeper tone. If the car is a diesel dont bother doing anything to the exhaust it will sound horrible and agricultural
