im guessing you mean you are wanting to upgrade to a k03s?
*queue the K03s, its not a worthwhile modification* brigade....
I would strongly recommend Miltek, they seem to be the chose exhaust on here, although they are veyr expensive
the DP & Race CAT are one of the best mods you can do to the ibiza as it really removes the bottle neck that strangles the ibiza
i have fmic , scorpion cat back revo and filter ..... am i going to expecting more power! much more and what bout noise??
cant wait
