IS-F Headers

I figured I let everyone chime in to see if it is worth going this route. Paul's fear is that we invest in developing this product and no one want to buy them cause of the installation charges. We are going to finish the stuff we are working before we start on the headers again.
Trust me you will be the first to know.

Hey Janoy,
Good to hear you guys are looking into these.. We passed it up a few months back..
One of the major obstacles is going to be running the headers without the primary CATs in place...
This will cause a Check Engine Light for sure as the readings are going to be off the charts, without them in place.
However, a set with some High Flow CATs might work.
I have not seen one working O2 Simulator for any 2005+ Lexus..
The OEM manifolds are wedged in there like no other!!
Regards,
Joe Z

I think someone already has a prototype on a car Joe... Let me contact them and see how they worked around it and how much they want for it. Honestly if they got a good product and a good price there is no need for us to make it. We will just sell their product.
Thanks for the heads up Joe!

Good luck with the R&D. Hope you can create a reliable product that makes good consistent power. Best of luck
I decided the same. I considered including headers for my build but decided to ditch the idea due to the Ecm and lack of tuning ability. I figured that i would come across a problem dealing with the Ecm. And since there is currently no way to tune/trick the car into thinking that it is performing to its liking the idea was scratched.

You don't want an aftermarket ECM for your daily driver. If it's a show car or a dyno queen, sure, it'll be great. But if the car needs to start and run every day to get you from A to B, you'll hate the aftermarket ECM. They're not even close to the same league the OEM ECMs are in. I'm not disparaging the work they do, it really is great, but at the end of the day, they don't have the time or the resources to fully reverse engineer the OEM ECM, so they get close enough to run and depend on the community to help sort out the individual issues related to making the aftermarket device work consistently in varying weather conditions and operating environments. The OEMs put a staggering amount of R&D into making their ECMs bulletproof. No aftermarket can afford this. So, if you decide to go aftermarket, make sure you've also got reliable transportation because your F won't be.
I'd love to be wrong about this, but I know too many Supra owners who have lived the pain. I was also the original person to talk to GEMS about using their stuff for a Supra way back in 1998, but I didn't have the resources to make it happen at that time. AEM stepped up and brought the resources necessary to make it happen so they work directly with GEMS to deliver their OEM replacement ECMs. Looks like GEMS isn't offering a 16 injector system yet. They'll need that for the 2UR-GSE.

Thats why i mentioned hydra. I know many people running double injectors and it can support more if needed for e85 (or gas, Water Injection/Meth). I ran one as my DD and had no issues with 1200cc injectors. Its all in the tune. The new stand alones are very capable of running todays cars and fully replacing the ECM sometimes even doing a better job then the OEM one. No need to make everyone fear the reaper, bc of a bad experience. (thats like saying a women shot you down once, dont go out bc they dont like to talk to men).
Now back on topic. Hopefully the other company comes out and has a product real soon for the rest of the community weather it be with hi-flow cats or not.

Sorry, but I have zero confidence the aftermarket will be able to make an IS work with an aftermarket solution. If all you want to do is run the engine and maybe shift the gearbox, it's possible. For everything else to work - not possible. There's not enough documentation to interface with all the ECUs required to run the IS. Ask Gernby about the mysteries just on the CAN bus.
