4-1 manifold on a 1.4 furio?

  1. #1
    is this a good idea because i dont like the sound of the oil filter movement but apparantly the 4-1 mani clears it.

    what are people saying?

    does it give you any performance gain? and whats it sound like?

    you will see a few bhp gain coz you will be removing the cat as well
    youll notice that it picks up and revs more freely

    Not sure about performance as i am still on my provisional. It sounds great very loud

    considering the mk2 manifolds are 4-1 anyway theres little to panic over.

    so would it be similar to the 421 manifold?
