is it worth...

    is it worth putting a 4-2-1 manifold on my vtr, i only have only got a supersprint back box on it at the moment

    so it still has the standard centre pipe with the cat

    so just wondered if it would be worth putting the 4-2-1 on it yet or wait till i buy the centre pipe which MAY be after xmas?
