Don't let that STOP you!

Get out and learn to maximize your current combo. Then, as you upgrade, you can see the improvement. I made my low 14 second runs with WORSE exhaust than you have.

Well there was a 3.5 altima with power mods that was doing some mid 14's that i did not want to loose to. I'm at 3440ft. And an altima definately has a wieght and 6 speed advantage.

Mid-14's at 3400ft with a 6 banger is pretty damn good!

Hey guys what ever happened with this? Did they ever finish the prototye? I will pay an extra 500 If he can get it to bolt right on to a GS 430.

Actually making some minor changes to the drivers side prototype. If I get the time I will update the committed list soon. Once final design is confirmed production steps can begin.

Basically a one off custom design takes time that is just not available right now. Lexus redesigned the manifolds for the 430 engines. It is POSSIBLE that the manifold flanges (head and catalyst) are in the same location. The bolt pattern on the head is the same. IF (BIG IF) the flanges are in the same location as the 2000 1UZFE... then the new headers would be a direct bolt in. I am not making this assumption. The only way to know is either test fit in a GS430 or have someone send in some GS430 manifolds to see if they will bolt into the header jigs.

For now, I am going under the presumption that they will NOT bolt in. This will require a custom Y pipe. This can be made from the stock Y pipe or contructed new. $500 will cover one without cats and make these a bolt in. With cats will cost more depending on your cat choice. Nice flowing metal substrate cats are available for under $150 each. Modifying the stock catalyst Y pipe would be easiest but will make returning to stock configuration (if ever desired) more expensive.

These are options I am not worrying about until the headers are actually built. Then we can find out for certain.
