I’ve finally reached the point of starting to put parts back onto this engine for the Silver S4 that I have made some upgrades to and have been performing maintenance on.
The XS-Power turbo inlets fit poorly so I cut the ends off near the compressor housing and fit silicone couplers instead.
The XS-Power downpipes fit well so far.
The same cannot be said for the XS-Power Bipipe that fits poorly. The pipes are in contact with the cam covers but there is still another eighth of an inch or so that the bipipe needs to seat further onto the throttle body.
May be time to look into a better quality bipipe; i.e used APR Bipipe.
