Had a resonator delete 2 months ago when i got the car for £60. Wondering whether i should get a backbox delete to make it louder... £150 ish.
Not loud enough with just a silencer delete definitely needs the backbox gone but does anybody know if this process has any drawbacks? How much worse does fuel efficiency get?
