Routing exhaust on slammed trucks

[tk-mpl]

Hey guys I am looking for pics of how you routed your exhaust on your trucks that are on air. I have a bolt in notch and dominators with 2.5" drop spindles.. I just put the box back on and there isn't alot of room under there. I am running the air lines into the front of the box aswell. I have the CPP trailing arm cross memeber so I can run the exhaust through it..

Thanx
Trevor

I have the same set up as you.

I don't have any pics yet but can get some. I just have stock exhaust manifolds to a cut down stock y-pipe to a magnaflow cat then a magnaflow muffler then a turn down before the rear axle. It sounds good but needs work as the y-pipe needs to be cut down more because it still hangs a little below the frame and looks like hell. I plan on having an exhaust shop do dual exhaust on it and dump them both before the rear axle. Simply because i'm not sure I can cut the y-pipe enough for it to tuck and not hit the engine/trans.

I just noticed you have an older truck so this may not help.

I talked to an exhaust shop and he said about $600, but will have to see the truck and how tight it is..
It is pretty tight right after the trailing arm cross member at full dump..

Looks good! Got any pics of it aired out where u can see how close to the ground it is at the tranny crossmember?

I'm running shorty headers with the pipes tucked up between the frame rails and through the trailing arm crossmember. My magnaflow mufflers are before the crossmember under the cab and I just dumped the pipes about a foot and a half behind the crossmember.
I dont like the looks of pipes out the back or sides but its louder in the cab.

You wouldn't happen to have a pic of it...... What size of piping are you using?

ok, got another question. I am routing the 1/2" plastic air line and am wondering how close can it get to the exhaust and can you insulate it?. The exhaust will probably be 1 1/2" pipe, how hot will it get??

Sorry man, I don't have any pics of it. I used 1 1/2" pipe. All of my airlines are run inside of rubber hose for protection from heat, road debri, sharp edges,etc.

Here is what i used to protect my tubing. i have lines running as close as 2 inches to exhaust protected by this stuff. I ran 1/2" hard line on the compressor/tank side of my system.

Here are some other pics of the exhaust from another thread. when the sun comes up, i will get better pictures of how low the exhaust sits when aired out.

Here are some pics of the truck aired out. In the 3rd pic and 4th pic, you can see the heat sleeving (blue) I used to protect the plastic lines from heat and chaffing. the LCA's and tranny cross member are the lowet part of the truck, but not by much.

Is running the exhaust to the outside of the frame an option? I ran into a similar issue with my '63, especially since I'm running 3" dia exhaust tubing and wanted to locate my mufflers behind the cab. The only way I could route the exhaust and keep everything above the bottom of the frame was to route the exhaust to the outside. I run a shorty swept-back header.
