Pretty sure I already know the answer, but how do you feel about the exhaust exiting through the panel? I mean having professional body work done. Not those cheap trim pieces that you cut a hole, screw 'em down and route the pipe through that. I'm thinking more of an arch(es) formed into the very bottom in the area in front of the right rear wheel. Have the tip(s) come out there. It'd technically be under the panel rather than through it.


NOT this:

Something like this, but way cleaner. Have the notch(es) match the tip(s):

Even if I was ok with that, there’s no route for it due to my 4-links being right there as well as the crossmember that’s right behind the cab. I’ll see if I can find a pic. I would need dual exits anyway, I couldn’t do a single exit. That would drive me crazy to not have one on the other side. I thought about all this long ago as well as a way to get it out the rear, maybe through the bumper. I just have limited room due to the frame height, rear suspension components, air lines etc. You have to remember the links travel a long ways up and down- I barely had room between the limits of them to run a single hard air line through on either side at a point fairly close to their pivot point in the front. There’s no way an exhaust pipe would work.

Got the Borla today and was able to temp it in place with the 3” downturn using clamps. It sounds pretty good so I’m gonna take it to a muffler shop and have them weld them in place and weld the hanger to it so it doesn’t bounce. The Borla is stainless and the rest is steel so I think it needs to be MIG welded?

A mig can do that without issue.

I think I have the leak at the RF figured out. The other day I left it aired up and popped the circuit breaker to the compressors (which tie into the main harness) and left it overnight. It lost no pressure. So I tried it again with the power to them turned on. It went to zero. In the RF only. Next night I popped the breaker and it did lost no pressure. Weird. Now, if I turn that power off the system doesn’t power up at all even though it has a wire that is switched with the ignition, so obviously the compressor power also is the main power to the manifold. There must be an internal short or something that’s causing the computer in the manifold to open the RF valve a tiny bit. But on another note, it doesn’t appear to be leaking out of the exhaust port itself which is another strange twist because if it IS opening the valve, that’s where it should be coming out of. AirLift doesn’t think it’s possible, never heard of this happening but they’re sending another manifold but needed a $250 deposit and if they can’t find anything wrong with it when they test it, I don’t get the deposit back. I do know I can’t find a leak so it makes sense to me that it’s leaking inside the manifold somehow. Might be an expensive mistake, idk. I’m out of other ideas.

Also, I haven’t heard a peep out of BT Diesel Works since I paid them $195 two weeks ago. I called and left a message. I emailed them. Nothing.

Well I finally found the leak on the left front. I installed the new manifold that Airlift sent me and I thought it was fixed. With the truck on jack stands I left it aired up to 150 lbs and it lost zero pressure for the entire day. So I let it off the jack stands and left it. It started losing air immediately. Overnight it lost 40 lbs. What. The. Fu*k. It pissed me off so I left it for a few days while I ordered new aluminum hard line, expecting to just replace that side from front to back. Today I put it on jack stands, pulled the right front wheel and put a jack under the spindle to imitate the weight of the truck being on it. I didn’t think it should matter- pressure is pressure, right? I sprayed the fittings at the bag first, planning on starting there and working my way back. Nothing. Then I decided to spray the entire bag. Aha. It’s leaking around the top flange, where a mounting bolt is. That’s not supposed to even be possible due to the design. But it’s happening. These bags aren’t even 3 years old, I replaced them right after I bought the truck because the PO had installed 8” bags which rubbed the control arms and put a hole in one. I think it’s a manufacturing defect. Anyway they’re out of warranty so I called Slam Specialties and ordered one. It will be here Monday. I hope this ends this leak issue. It’s been driving me nuts since I have owned the truck. Before the new Airlift system it used to drop both fronts down overnight if I left it aired up because I only had a 4 valve setup so both fronts ran off one air line. I mean, I always air it out when I park it so it isn’t critical but if I drop it at a shop I need it to stay aired up while they work on it. Plus it’s just annoying to put so much work into new hard lines and a new air management system and see a slow leak.

Glad you found the leak Mark. What a PITA. Hope this addresses it once and for all.

Thanks Sam. I’m still gonna try to get my $250 deposit back from Airlift on the manifold even though it doesn’t look like it was the problem. Hopefully they’ll just give it to me without a hassle.

I officially declare the air leak issue resolved. I replaced both front bags so now all 4 are brand new. Here’s the pressures over the last 24 hours. I attribute any differences to the temperature change between yesterday’s 92 when I originally aired it up to today’s 73. For the first time since I’ve owned this truck I can leave it aired up and it will stay. That was a hard leak to find. I would have found it sooner I think if it originally had 2 lines going to the front instead of one because it would have occurred to me that it was a bad bag I bought right after buying the truck instead of thinking it was a line. The entire front would go down with the original air management and then it was just the one side. And only if the weight of the truck was sitting on it. Shit.
