So as many of you know I pulled the motor apart on dropouts car! Here are a few pics for the less than satisfactory factory manifolds!

Thanks so much for the picts. Actually they look better than I expected. However, it looks like the right side will flow better than the left. A real collector on the right and the left side seems to have one cylinder directly in the flow of the other three. Do you see a reason for this?

I'm assuming any headers developed will have built in high flow cats???

Yes cats will be available.

Will you have to pull the engine to install any aftermarket headers?

I can't believe both Lexus AND Yamaha accepted such a pathetic design for an exhaust manifold. Granted there's no room, then make the f one. Geez!

I don't know this engine bay too well since I haven't bought an ISF yet, however the designers have to take into account smog and other regulations.

It would be pretty interesting to see the final product and the dyno sheets with Joe Z exhaust and intake in addition to the headers.

Those are numbers I would like to see. Perhaps we can crack the 400whp.

Hmmm...There's a Pepsi can integrated into these manifolds??? No wonder it's running rough. Must be some shameless advertising on Pepsi's part.

Considering I've seen 380 with the exhaust and intake, 400 is pretty much there once everything is installed/running.

* This will give the M3 (Perhaps some M5??) guys something to chew on.

I get the humor about the Pepsi can..........haha.

Researching this car is pretty fun.

Great! Thanks for the Pics Andy. If you want to team up on anything let me know. I just purchased a 3D scanner and so far the results are pretty sweet. I am mostly concerned also with access, seems like an engine drop to get to. Glad to see a place that obviously smog took its toll.

Here is a bit of a sneak peak! I have about 15 hours into what you see in this pic!! These things are tight! I was going for equal length, but I would have 300 hours into just one side if I go for that. Sooooooo........ I'm just going to do a nice flowing set of headers, I have done a bit of the math and it really shouldn't make that big of a difference in power. So here you go!

Looking good so far. So, will a free flow cat be attached to the end of each side, or are you just deleting the cats completely?
