Challenge to install but well worth the outcome.

The manifolds and up pipes made a huge difference for noise, temp reduction, turbo spool up and throttle response. Manifold removal was pretty straight forward but the up pipes was a pain. Reaching the bolts that connect the up pipes is difficult due to there being very little hand room behind the turbo and engine. Once you get the up pipes switched out everything else goes together pretty quickly. Only thing I recommend if you are going to do this install is that you have a three prong grabber on hand in case you drop a bolt as they are not magnetic and are a pain to pull out of tight spots.
