    You did mention in the another post doing a Relentless Downpipe and Cat a few weeks ago on an S3!

    based on your feedback regarding the fit of the system, I am dreading to start on mine. but I will share the info once it is fitted!

    I still hope there will be no need to trim anything off.

    Does anyone know if I can scavenge the old screws and bolts for the joint between the DP and sport cat! what do I do with the turbo screws are they ok to use again with the new DP? please let me know as I will do it tomorrow, since someone is giving me a hand. else where can I buy bolts? of the shelf on a Sunday i.e. eurocarparts? Loydsmotor?GSF? any help is much appreciated.

    Just an update, I have fitted the Relentless DP and 120 cell cat today, what a rubish fit! it took 6-7 times to grind and increase the hole sizes for everything to come togther on top of this, it is very ristricted, and would hope I dont ever have to go near it again. other than that sounds really good, you hear the turbo all the time, very responsive and above 4K feels a lot quicker than it used to. overall I think it gained around 7-10 BHP and a little more torque. coupled with milltek non res, sounds nice.

    The rev moves a lot quicker it is almost like having a light weight flywheel! just love the sound though.
