Ok Guys, I got a thought in my head.

This whole camper and towing my jeep thing is bothering me. The only thing holding me back from using a truck camper in the Cummins is my nice and shiney 7" stack. To sell my trailer, buy or build a new one with living quarters would cost alot more. Cant buy a enclosed because they are to short in height so that would mean custom = more money.

Where the Exhaust 90's up into the bed, replace that with a Y-pipe. Build up some flanges for both ends and the base of the stack. Also a cap for the bottom side.

Wanna used the truck camper? Unbolt the stack and the cap....Cap the top of the y-pipe with the cap from underneth....Now I have exhaust dumped underneth.

I've thought about noise too...Never had exhaust dumped under the bed. How loud would it be? I do have a 12" Muffler, but no cat.

What do you guys think?

I know if it was straight piped and dumped underneath it is loud.. If you wanted to go extreme. I think grand rock makes a diverter pipe. So in theory when u take the stack off you could use your stock exhaust.
But this is just me thinking out loud.

 

I know where you can buy a truck camper. It's sitting in my yard, Glenn has it for sale.

 

I did something very similar with an old car. I put in a "y" with a plate over it. When I went to the drag strip, open the plate covering the flange on the end of Y, wide open exhaust. When I left the track, three allen screws and I was back through the mufflers for the drive home. You just have the added extra step of removing the stack. I think it will work.

 

Do you like the stack to the point you wont get rid of it completely?

 

With your fab skills you can make it very simple. Make and install a 3 bolt flange. Not sure if anyone makes them for 4" but you can make them out of some 1/4" plate, but make 3 of them. weld one to your exhaust pipe at the rear of the cab. Now modify your stack set-up so that it bolts onto the pipe using this 3 bolt flange, and whatever mounts the stack to the bed.

find someones old 4" tailpipe who went to stacks or just get some pipe and make an extension/tail pipe that runs back under the bed with a turn down, or angle out in front of the wheel. you could even install a hushpower or similar muffler in this extended section to quiet it down even more if you like. Also you would need a single hanger on the pipe running up to one of the original rubber isolators under the bed, i think there should be one before the axle. Wouldn't be hard to make (i've seen your fab work on the jeep so i know what you can do) and when it comes time to load up the camper for the weekend, you can change stack to shortened tail pipe in a matter of about 15-20 minutes.

 

How old and how cheap?


Yeah I do beleive this will work. I'd perfer to get it as far back under the truck as possible, but I dont want to interfer with suspenion or bending up a whole tail pipe....

You know, KISS, Keep It Simple Stupid.

I found one in decent shape on the Shore I may go look at. I dont want to spend big money on a camper I'll use 5 times a year. So the basics is all I need.

Glenn's is a 2001 and he wants 4k obo iirc.

 

Too new for my budget....

I just payed off alot of credit cards...so its nice having cash again....but knowing me It will be difficult to not buy something newer.
