on my99 turbo i have just fitted a new magnex s/s system from the first cat back,straight through to backbox.(very loud)
how much more power will that give?
also fitted bailey dv well impressed as a first time scooby owner. until i started to read some of the threads concerning dv's. to be honest i am a bit niave when it comes to mods, so really haven't a clue about the technical stuff.
can someone explain a re-map to me-will i need one,how much?,who does them?
sorry about all the questions but am new to the scooby scene and don't want to bollox me car..
