Through side bed exhaust

[daking]

Building my exhaust. I decided I wanted to run the pipes and muffler high in the frame, and have nothing exit under. So I cut a hole in the side of the bed, and ran exhaust there. 

 

The muffler will mount high under the bed, just in front of axle. Its a same side IN / OUT. Its a larger muffler, for a deeper sound. 

 

I'll be putting an 8" flex pipe near header to prevent header cracks. 

 

I'll be wrapping the headers (already done). And wrapping most of the exhaust piping. For a few reasons, one the pipe runs near the transmission and I want to keep heat down.  And the hotter the exhaust gasses the better the flow. An Exhaust that runs too large of a pipe, or too long of a pipe will have issues, as the gasses cool. (Its dry where I live, so I'm not worried about rust due to moisture in the wrap)

 

I'm going extreme on the mounting too, to insure proper weight, and strength. multi rubber isolators.

I like it. I've been considering doing the same rough thing to mine.

That looks a lot less terrible than I was expecting. Though the only time I've ever seen that done has been on diesel ricers who run giant 4"+ pipes out the side. That actually doesn't look half bad.

couple years back i had a off road magazine that had zone offroad"s MJ build that ran there pipes out through the side of the bed, but they did it just aft of the rear tires. i like the idea of it. are you going to cut your tip flush with the sheetmetal?

Some up dated picks. really only got the down pipe done, so far..

 

Flex joint, 2.5" pipe.

Finally done, took awhile. other things came up and what not... anyway,.  It came out just like I envisioned. I wanted to tuck the muffler higher, but it should be fine where its at. 

 

custom 2.5" down pipe with 2 O2 Sensor ports (factory and wide-band). 

2.5" flex pipe to prevent stress on header.

2.5" band clamp to allow easy removal

heat shield on exhaust pipe near transmission

long straight mid pipe 5ft long. ( I'll add a Cat there)

muffler mounted under bed, in front of rear axle. same side IN / OUT. 3 hangers for support. Band clamp to allow removal of muffler.

Pipe bent up and around the frame for exit.

burnt blue exhaust tips.

 

Tip, mounted angled down a bit

That's cool I like it, is that a FM 50? Post a sound clip pls.

[Tommy]

Very nice. Let's see a video

[daking]

Well finally started the engine! 

 

Here is it idling, and ~2000RPM

 

Kinda sounds hollow, or tinny.  I was hopping for a deeper sound. Maybe I'm used to V8's. I think I'll put a high-flow cat, hopefully that will take out the tinny sound. 

 

 

So, let me know how you all think it sounds. 

[Tommy]

Sounds pretty good. Not v8 good, but better than I'd have expected from that engine. Looks great, too. I'm inspired.

[Randerson88]

What muffler is that? trying to get as close to a V8 sound as i can get out of mine.

[conker]

What is the offical name for that piece you have bolted to the bed side that the exhaust is coming out of? I'd like to run a similiar dump at some point.
