Headers on 1FZ-FE engine 1997 Landcruiser (1 Viewer)

[thelal]

Were you able to find a dealer?? I can't seem to find any AUS willing to ship to NA anymore.

I've it coming on a container (someone (house) moving back to Ireland - where I am); Waiting another month or so before I get my hands on it and then will see how it fits etc.. can report back then. Found via expats-in-Australia (FB group) so might be an avenue to try

Resurrecting an old thread (again). Any long term thoughts on how the CXRacing headers held up?

I’m running the ph12650 and the phb100p.
I chose to run with inside the frame so sliders were easier and the exhaust is less exposed to damage offroad.

Thanks for posting this info. I ordered this setup from AUS and I'm looking forward to getting it setup. Just need to weld some o2 bungs.

My CRX headers are coming up on six years old. I still love the exhaust sound on startup. The only issue was early on with the nuts and bolts where the 3-1 pipes were connected. The lock washers lost their tension due to the heat and vibrated loose. This is above the section of flex pipe. I replace the four with longer bolts and did double nut. Bottom nut flanged with the ridges to lock instead of a washer. Supercharger caused a little surgery to be needed as the #3 pipe stuck up too high.

Thanks for this! I have the CXRacing system on my 96. I had to order a new downpipe from them because one of the flex joints developed a huge leak. I had the new downpipe installed by a shop that was doing some work to my AC. On my first long road trip, I developed a leak at the flange connections between the headers and downpipe and it melted my washer bottle that's relocated by the firewall. When I looked under the fender, one of the flange bolts was missing the nut on the bottomside. I bought some nuts and bolts to get back home and took it back to the shop that installed it. They replaced the gaskets and installed new bolts and nuts. I picked it up and within 15 miles I had a leak again. It looks like when 1 flange is flush, the other is off a few degrees but you would think the "flex joints" would allow them to both mate up flush. I'm going to try the double nut trick to see if I can make it work.

Anybody see any mpg increase from the headers/cat delete?

I haven't noticed any significant increase....slight but not significant

Been a couple of months since I used the double nut trick and everything seems to be holding! I haven't been on a long road trip but plenty of highway driving and a short 2 hour trip and no leaks. I think I'm free to reinstall my washer bottle!

I would say improved seat of the pants performance but not much MPG improvement. I went with a 3" custom exhaust and kept a single cat. Intermittent CEL for lean condition. Currently no CEL!
CXRacing headers will delete your EGR! There is no channel cut for the #6 exhaust to port to the EGR.
CXR vs stock, cursor at #6.

Anyone use these on a carbureted 1FZ-F and H150 manual tranny?

No emissions / O2, no computer etc
