Help me build an exhaust

Put your headache rack and and build the stack braces off that. Leave the cab alone.

 

Just put stacks behind the cab and infront of the headache rack. I have a 9400 mid roof with the single rear stack and will be converting it to duals side stacks from a salvage yard donor.

 

You’ll have to pull out a good chunk of your interior to get down to what you’re looking for. That looks like a thin plate used as backing for the cabinets to mount to.

 

It is easy to install dual stacks behind the sleeper, you need to get the frame muffler mounts off of a factory dual stacked truck from a salvage yard, and may even have to move the battery box, but easy. The frame mount on a single stack truck is actually built on an angle, or at least the ones with the curved exhaust tip is.

A friend of mine with a T600 did not have a lot of room behind his sleeper, but wanted an enclosed headache rack. I ran straight stacks through the inside of the headache rack, and it worked well for him, and looked good too.

 

It is easy to do with cheapo salvage yard parts, and lots of the 9400's in salvage yards. I changed mine up, using a cheap parts truck I bought.
Mine originally had 100 gallon tanks and full side skirts, I had built some hidden boxes and installed a 150 gallon extra tank. I removed all that along with the skirts and installed dual 150 gallon tanks, installed the small fenders for the steer axle, relocated the battery box and air drier too. I have not installed duals yet, because the previous owner of the parts truck had removed one of the straight brackets and changed to a single stack. he had gotten rid of the other bracket. Once I get another straight bracket I will install duals and the way they are built, it will be easy to build a nice headache rack between the two, using them for the sides of the rack.

 

Had this box built for my 9300. Mounted the mufflers to the sides of the box. Very simple and functional. Originally had the duals on the back. Saved a little weight by ditching the factory frame mounted muffler brackets,and mounting directly to the box.

 

Looks good, got anymore pictures?
