Put one of each of those on the ends of your inlets, where your arir filters used to be. Plug the pcv heater hole on rear inlet. Insert air into system. Listen for leaks.

Google boost leak test n54.

I don't think mmp inlets have the rear inlet pcv hole. my relocation kit doesn't, it just vents to atmosphere from valve cover through a hose.

Jesus, move on with your life. You're like a sullen child. If you took all the time you spent complaining and invested it in whatever job you're working, you would have made the money to buy a different set.

Lmaooo. What a sheltered life you live.

But to add actual substance to this thread. I have already determined if I have problems with either inlets or outlets, I am just going to cut the problem chunk out and join in an aluminum pipe.

or have someone that knows what they are doing install them. Not doing it in the drive way with a brick, a floor jack and a hammer. I installed a set today and its got a ton of clearance.

Did you use a curved pipe? Or just an angled pipe? I assume a straight pipe would not fit given where the manifold can hit the outlet pipe. It looks like it is on a bend.

Did you consider making a bracket to hold the new part of the pipe away?

Off the shelf pipe? Or did you just cut a straight 2" aluminium pipe.

Did you add a bead to it for clamping reasons?

Just curious. I have the same inlets and it's hard to get a good pic without removing the rear inlet pipe. I Appreciate the pic. If you could remove the inlet(you don't have to) we could see the full fix.

Thanks man!

Mine split (didn't melt), so I did the same with aluminum pipe and a couple of clamps. First pic is before the split to show the positioning close to the manifold (the heat shield tape is peeling off), second is the outlets with the split, third is post-install directly from the top, fourth is a bit more from the side to show that the outlets have been shortened a bit and now have a downward angle, keeping it well away from the manifold.
