    An EWG has little to do with the downpipe or turbo-back exhaust! Unless you are planning to dump the wastegate back into the downpipe, the Uppipe is the piece of the exhaust with which you will be most concerned. Pay special attention to Header designs as well, as many ELH are not compatible with V-band EWG setups.

    That's OK, there is plenty of information on this board

    It is in your best interest to keep these comments to yourself, as this sort of negativity reflects poorly upon yourself and specifically violates our forum policies. Consider this a warning.

    Edit: on second thought, I'm removing the quoted comment as it lends nothing to this thread (OP, you know to what comment I'm referring).

    As Zach stated, EWG has little to do with your turbo back exhaust. I would recommend buying an EWG uppipe rather than trying to make your own.


    We will need to know what headers you are using, what EWG you have, and what downpipe you have (some downpipes, TurboXS for example, make EWG fitment difficult).

    Also depends on the EWG you're using. I have seen several reports of the GrimmSpeed pipe location NOT fitting with the TurboXS downpipe, as well as the TurboXS EWG pipe not fitting either. I'm pretty sure the lower profile of the v-band attachment of the newer Tial MV-S and MV-R EWGs aids in tight spots. The only two uppipes I have seen with guaranteed fitments with TurboXS downpipe are GTSpec (which I don't know if you can even get anymore), and P&L.

    My P&L 44mm EWG uppipe fit fine with my TurboXS downpipe. ::cough::and it is also for sale!::cough::

    Just as a note, the grimspeed kit I got I had to modifiy to fit with the new Tial v-band. Apparently the kit was designed around the turboSmart v-band flange, which at the dump side, is slightly smaller. To resolve this and use it with my Tial, I had to carefully sand down the flange on the dump tube.

    OP, you really should do some reading on the subject to understand a bit more when leaping to an EWG. It's not really a 'plug and play' mod in my opinion. Your tuner can get going for you and everything... But I feel it's useful to understand a bit of what is going on under the hood at that point. Understanding the basics of your boost system can help you diagnose or at least identify any issues while driving, before they blow your engine up.
