daking Posted November 9, 2014 Share Posted November 9, 2014 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. (Exhaust is not not done, that tip is just hanging in these pictures) Image Not Found Image Not Found Link to comment Share on other sites More sharing options...
Tommy Posted November 9, 2014 Share Posted November 9, 2014 I like it. I've been considering doing the same rough thing to mine. Link to comment Share on other sites More sharing options...
Motorcharge Posted November 9, 2014 Share Posted November 9, 2014 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.

87mjdriver Posted November 10, 2014 Share Posted November 10, 2014 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?

daking Posted February 11, 2015 Author Share Posted February 11, 2015 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 Posted February 11, 2015 Share Posted February 11, 2015 Sounds pretty good. Not v8 good, but better than I'd have expected from that engine. Looks great, too. I'm inspired. Link to comment Share on other sites More sharing options...
Randerson88 Posted February 19, 2015 Share Posted February 19, 2015 What muffler is that? trying to get as close to a V8 sound as i can get out of mine. Link to comment Share on other sites More sharing options...
conker Posted February 19, 2015 Share Posted February 19, 2015 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. Link to comment Share on other sites More sharing options...
