mr. cob Posted October 13, 2016 Report Share Posted October 13, 2016 Howdy All, I have been looking for an dual stack setup for my Freightliner Columbia, ever since I bought it, I found a set in Idaho, the price is right and the salvage yard will install them so all is good. Cost of installation depends on how long it takes which brings me to my question, If I can remove the nessisary interior panels and then reinstall them myself I would save a pile of cash as I could have the truck ready to have the holes for the pipe mounting brackets drilled BEFORE I get to the shop and then reinstall the panels at my leisure when I get back home. So if there is anyone at the rally who knows how to do this and wouldn't mind giving me some pointers on how its done, please contact me, I am in site #52. THANKS.

I'mdonewiththis forum Posted October 14, 2016 Report Share Posted October 14, 2016 Mr. Cobb, you shouldn't need to remove any interior panels for an exhaust install. The exhaust will come from the turbo, run under the cab, into a wye, then to each stack. The stacks normally have a couple of rubber mounts to hold them in place. We can discuss things tomorrow if you want. Link to comment Share on other sites More sharing options...

Howdy Tom, Holes will have to be drilled in the sides of the cab on both sides, the holes are needed to bolt the support brackets to the cab, the brackets then support the pipes. Looking at the same pipes that are mounted on Bill's truck, it looks like there are studs that go from the outside of the bracket through the cab and are then held in place with nuts and I am assuming a backing plate of some sort. So I can't see any way to do this without removing the interior panels on both sides of the cab. That said, I'll admit to NOT knowing what I am talking about just can't see any other way of doing this task.

RandyA Posted October 14, 2016 Report Share Posted October 14, 2016 Have you considered using blind steel Rivet Nuts? They can be set without a special tool - just use a grade 8 bolt with flat washers as spacers to pull the butt in. No need to remove internal panels. The holding power in sheet metal is impressive. I've used them in thread sizes ranging from 1/4" to 3/8" and have never had one pull out. From Amazon.com: WHAT IS A Rivet Nut?A Rivet Nut fastener is a tubular rivet with internal threads. It can be installed in seconds form one side of thework. Once installed, no finishing work is required on the Rivet Nut fastener. The added benefit of not only being a dependable fastener, they are ready to use with clean threads available for screw attachments. Blind thin sheet materials that are too thin for a tapped thread. Blind Rivet Nuts also are used when an application has little or no access to the backside as they can be installed from the front side of the work piece.

hdonlybob Posted October 14, 2016 Report Share Posted October 14, 2016 My Volvo 610 had the interior panels fastened with heavy duty velcro....easy to pull off, and will go back on very securely.. May want to check that out.. Cheers, Bob 1989 Safari Serengeti 34'Towing a 1952 M38A1 Military Willys Past HDT owner Link to comment Share on other sites More sharing options...
MrSeas Posted October 15, 2016 Report Share Posted October 15, 2016 So did you get the panels removed? If so how did you do it? Link to comment Share on other sites More sharing options...
CDR Posted October 16, 2016 Report Share Posted October 16, 2016 Dave; The interior uses "Christmas" tree type of push pins. They slide in cutouts on each panel. If you get an automotive trim removal kit, this will allow you to pull the "soft" panels. Then you can access the fasteners for the hard shell outer trim. Let me know if you need more help!
