It's not stock.

I'm trying to get this 55 back as close as I can to how it rolled off the showroom floor. I agree it's a terrible design but I don't ever plan on taking this vehicle on anything more rough than a gravel road. Most of the 55's I have seen have a lift and bigger tires. Someone has to make it look stock. If not we will never be able to appreciate how really looked. Have you ever seen a Pig with 27 inch tires?


This is my goal. Heck it even has larger tires.

Oh baby! ok see your point. My 74 looked almost exactly like the picture above when I got it. Stock IS sweet so all I can say about this subject is the stock heat shields in 10/74 were outside the frame rail. Maybe You could track down some ad pics for your cruiser.
 
lookin' good....I crushed my pipe on my '77 that ran beneath the frame...

it is nice to see one almost stock!

Hmmm, I know you guys are looking for OEM exhaust routings but I was just thinking that I had the exhuast re-routed up under the tranny skid for protection on my pig. I did not even think about heat/drivetrain issues. Is that really an issue? Has not seemed to matter with my trail pig so I recently did the same to the exhaust on my other pig. Doh.

Would think that the pipe running next to the tranny is no big deal. More of a point of argument for running the pipe outside of frame rail. It just goes back to the basics. Less heat is better for the tranny, transer case. I also don't like the pipe running under or near the gas tank fill. Probably another no big deal but with all of those rubber gas hoses right above plus the potential for gas vaporization (on contact with the hot pipe) and boom if fuel is spilled. If you cruise by the Chutes' or the high lakes and see a pig pink (navaho brown) 55 thats me. Stop and say high if not fishin, hours sun up to sun down.

More hijacking...

(Well, it looks like myself and a couple buds will probably be heading up towards the Three Sisters Wilderness tomorrow to check out the snow level and get a last time on the roads/trails up that way. Are you going to be in the area tomorrow? Hee, hee. I'll keep an eye out for you in the future.)

Thanks for your thoughts on the exhaust routing also. :)

YOU DOG! Three sisters! Me jealous and tempted........ If you ever get the chance, take the road off of Cascades H.way by Bachelor north to that (can't remember name) lake under north side of Broken top. Tam Macan ridge. True Oregon tour, not that rough but Spectacular! Landcruiser landscape!
 
Marshall, my heat shield is on the outside of the frame rail like rsbcruiser's......my exhaust had been modified though cause of the heat buildup underfoot in the south it is a pain <LOL>

untill you showed the pic Trollhole I never would have believed it. But there it is. Over the frame to the outside, back under the frame to the inside and then back under the frame. Why? I just don't get it.
 
While on the subject of exhausts, did fj55s ever have catalitic converters? If yes, what year were they added? I was looking through these pics and noticing that none of them show a cat. My 1972 pig is also cat free, but those stock mufflers were huge!
 
Here's an underbody photo of my piggy. The frame is a '76 the body is a '74 or '75, I'm not sure which. The heat sheilds are both stock and in the stock locations. I do not run a muffler at all on the turbo diesel and since the 3B exhaust dumps on the opposite side of the engine to the "F/2F" the exhaust must cross over behind the transfer case to get to the hangers and heat sheilds.
