    Would a Z20LET de-cat pipe fit a Y20DTH (2.0 DTi)??

    As the title really...

    Will a Z20LET (2.0 Turbo) de-cat pipe fit a Y20DTH (2.0 DTi). I heard a rumour that the exhuast systems were very similar...

    Any help appreciated

    I would say it is possible but you will need to do welding on it. If I remember right the y20 is a clamp fitment to main system but the zlet is a flange fitment

    Someone's been sniffing diesel. The Y20DTH's turbo is at the back, the Z20LET's turbo is at the front, so I'm guessing you've realised it's not a straight swap.

    When I had mine done they just hacked the cat off and welded the system on at that point.
