These manifolds flow well and are built to last with zero failures to date!
P.E.P. manifolds are 304SS throughout! Never worry about rust or failed coatings.
Utilizes 1/2″ flanges 4 mm thick walls to ensure strength with a low weight
Positions the turbo in the stock location and is flanged for all T2 turbos (including but not limited to the stock turbo)
All Manifolds include:
An O2 bung in the collector for the stock primary O2 Sensor
An EGR fitting which is positioned so that you can reuse your stock EGR tube, but the tube may need some slight adjustments in position for a perfect fit.
8 x black oxide socket cap bolts to replace the factory manifold bolts or optional upgraded stainless bolts or ARP stainless studs and nuts
Installation tips:
Use Anti-seize on all exhaust hardware
Use optional studs wherever possible
Cut the short end of an allen wrench down to about 0.75″ in total length so it can fit into some of the tighter spaces (such as the center bolts)
Ball end allen wrenches will be very helpful throughout the install.
The M20 threads on the EGR fitting can be very difficult to start especially if the alignment isn’t perfect. To make things easier loosen the EGR tube support bracket near the water neck and the nut at the intake manifold. With these loose, it becomes very simple to get the EGR fitting started at the exhaust manifold. Snug everything down once all threads are started.
