This part gets rid of the EBV actuator linkage that obstructs the lower 8mm 12 point bolt - one of three that holds the outlet on. Of all the bolt reputed to be difficult to remove on the entire turbo, this one was the worst (used 8mm 12 point 3/8 drive deep socket, long handle flex head ratchet, removed the lower bolts on the exhaust downpipe). Unfortunately, this new part still has the casting for the EBV mechanism (see picture - the solid cylindrical appendages) - I think that's what it is, it appears to serve no purpose. These are worse obstructions to the 8mm bolt than the EBV linkage and mechanism itself. It may be possible to grind these off. It would be better if Riff Raff developed an outlet without the appendages. It would make 94-97 turbo removal/installation much easier.

Flows dope as f***

My EBPV was leaking oil badly so I deleted it. Wow what a difference in EGT's. At least 100-200 lower while cruising. I dont know if mine was working correctly or not but wow what a difference. HIGHLY recommend doing this high flow outlet.

This is an exact fit slide right in and helps make getting the turbo on and off easy. I live on Mt Hood and it has made no difference in how my truck warms up.

What a great option. This is a great turbo. Love the performance. Inalso added the Riffraff billit wheel and am truly amazed. Another great product. Thanks Clay.

easy install exact fit thanks really hear the turbo now

nice to have full flow and get rid of my problematic engine brake et. al.

So long story short, if you want your OBS 7.3 to breath and sound AWESOME, then this is definitely a MUST! (of course, you should do the accompanying mods also)

Installed this the other day. Took maybe 20 mins total time. I love it. It also changed the sound of the truck. Sounds like a monster!!
