At any of the local auto part stores. You just put it on the gasket's in between the flanges. Pretty simple! :)

For the 4x4 guys, Bryan at Berk asked that you contact Berk directly using their contact page to get a replacement driver's side b-pipe. Do not send Private Messages through TT.

regarding the gaskets and sealant:

For the gaskets I reused your OEM gasket with just a small amount of RTV on the metal gasket. I then used the supplied Berk gasket on the rear. Here is how it goes. You only need a tiny bit of RTV for safe measure. They will rub it between their fingers and just leave a very thin layer. It probably isn't really needed but won't hurt being extra cautious.

STOCK: header / ring gasket A / OEM Bpipe / metal gasket B / exhaust

MODDED: header / metal gasket / Berk Pipe / Berk gasket / exhaust
thanks bryan!

I think I used the wrong stuff on the gaskets. What I used hardened up so I'm thinking it was not designed for use with gaskets in the flanges. I'm going to have to visit the parts store and see if they have something different.

My experience with ultra copper on bare flanges that are flat and line up properly, it will all squish out if you tighten the bolts tight, and then it will leak. So I think you do want to use it with gaskets and not as a substitute for gaskets.

Still working on the 4x4 version, I heard it should be "soon" but that's a pretty subjective word. If it's not now, it's not soon. :)

I have a 4x4 also and have my other components to install, just waiting on Berk and hopefully a 4x4 group buy.

has anyone with a 4X4 got an update on the b-pipes yet?
I was told that when the new parts are available, they'd issue a UPS call tag to have the original left side part picked up and would ship a 4x4 version in its place. So in addition to the original 'free' (included) shipping, they're paying all the shipping both ways on the replacement.

I thought that was really above-and-beyond, and takes out a little of the sting from the parts not having been test-fit to a 4x4 originally... And I am not in a huge hurry so the wait is merely an inconvenience and a low-level one at that.

What was conspicuously absent from the assurance that they'd handle the logistics was any mention of "when." Clearly they have the measurements they need to make 'one' 'cause we've seen it. I'd expect they'll want to have actual production-grade tooling and fixturing when they are going live with multiples tho.

I got my mandrel 2.25" 90 bend & 3/8" thick 2.25" flanges yesterday. I test fit the 90 under my truck & it look's like an exact replacement for the crush bent 90 i have now. Just need to make an appt. to get it welded up, so i can install my B-Pipes! :)

If anyone is interested i got these @ Mandrel Bending Solutions Home Page

Those who have them should set their phone or camera under the transmisssion crossmember facing upwards. Take a video of the stock set up, then after the swap, another at the same location for the after video... That's where you will really hear the difference in sound, there is definitely no doubt that the exhaust coming out the rear is louder too because of the increased flow...

Bad 24/7, the video did a good job of showing the sound difference. I should have done a before/after check using my decibel meter. :(
