Exhaust Re-Route

S

possibly a ghost :(
I'm about to have the exhaust re-route done. Does anyone have any lessons learned from doing this? Something I should be concerned with?

Adds a couple inch's of ground clearance. I didnt do mine and i wish i had, still might. But already have my Mobtown skids been mounted for about a year, heavy bitches!

The exhaust tubing that comes from the left cylinder bank is the lowest hanging part of the truck besides the LCAs and differentials as it crosses beneath the crossmember and transfer case. It's very vulnerable to damage, and pinching your exhaust shut on the trail is not a cool thing to have happen... especially if you don't have a Sawzall handy to make an emergency repair. You can protect it with skid plates but this takes several inches of ground clearance away in that area. Re-routing it prevents all of that.

@CWebbyExploreX4 the only special consideration I would have is making sure it's not routed too closely to the transfer case actuator, and making sure that it is heat shielded even if there is a few inches of gap. Those actuators are a weak link anyways (it's a plastic housing with soldered connections inside) so introducing more heat to it is probably not a good idea.

meh im just gunna go URD when I finally get some mullah for it. damn this truck is costing me

URD is not high clearance, unless they recently started offering a HC version. And they're probably charging $600+ for something that a muffler shop does for $160. Just sayin'.

400 on the newest ver 2. still higher clearance than the factory. my problem is if I was going to an exhaust shop id want a total custom mandrel bent exhaust. flow flow flow

Thank you for the advice. I'm having someone do it, but I'm pretty sure I'll need to find and install the heat shield myself. Any recommendations?

As @OuTkAsT said... The cross over is almost center of the truck and sticks down about 1.5" below the frame cross member. First time I took it off road I scraped it as I crested a hill. Not cool Toyota!

I'm bringing my shop a plate to weld on for a permanent heat shield. Lots of guys use the wraps that clamp on over the pipe but if you live anywhere corrosion is an issue I can see those being problematic since they can retain moisture.

Ok so they're on version 2 which looks much better but that $500 price tag hurts. Could have an entirely custom mandrel bent exhaust made up for that much at a muffler shop. And I'm not sure I like the idea of the pipe heating up the transmission fluid being that close to the belly pan either. Meh, to each their own. It's definitely an improvement over their original.

This was my re-route. I used a clamp on heat shield where the pipe passes near the actuator.

I was paranoid about the actuator so I took some temp readings and the actuator was actually warmer the the shield so I'm not too concerned about it anymore.

I still need to have them do mine. Good to know about the temps. I actually cut off the piece of the OEM heat shield that protects the spare from the tailpipe since I cut that section off and I'm just going to have them weld it back on the front of the crossover pipe.

That's a good idea. If I remeber theres a small bolt on heat shield under the transfer case that becomes useless once you re-route. Relocating that could be another good option.

I know yours is a 3rd gen but that looks a lot like my reroute on my 2nd gen. Interested in that heat shield as the shop that did mine did not like the wrap for anything so they persauded me to not do it. Did you fab it yourself?

I've read bad things about the exhaust wrap so I used that Thermo Tec clamp on shield. It just attaches with hose clamps. As far as re-route I had performance muffler of Phoenix do the work and install an electric cut-out. I just did the wiring and clamped on the heat shield.
