Exhaust on Type S

[TypeS]

Why is it then that TODA headers improve power & torque everywhere, particularly low end & part throttle power.

Anything with a 4-2-1 long tube design, is going to improve torque and power, all over the range, compared to the stock manifold. Heck even a shorty, will yield better results than the stock. That is not the point. My point is a custom designed system, aimed at low end, will perform better at the low end, than your TODA, comprehend?

I for one hate dyno’s, but if it will help get the point across, then so be it. I've seen numerous dyno's of the TODA header, and they all show power skewed to the top end. I'll even throw in an example, the following dyno is a comparison between Toda exhaust + Stock headers compared to the full system.




Now show me, where these Toda headers, “particularly” improve torque and power in the low end. The gains are particularly in the top end, are they not?

There's no real shift in the torque, rather a total increase, accross the board.

You’re kidding right? Explain to me how torque is created magically by your headers?

Headers do not increase torque they merely shift the torque curve.

Primary pipe diameters, determine where the torque will occur. Smaller the diameter, lower the torque. If you make the pipes larger, you sacrifice on low end, for the benefit of top end. Similarly primary lengths do the same. If you want me to go into further detail I will.

Now as for Torque, it is a twisting force, therefore it is dependent on displacement .
Have you ever heard of the saying,”there is no replacement for displacement”? Increasing the displacement increases torque, not bolting on a set of extractors.
Similarly torque is increased by shortening the gear ratios, shortening the bore while lengthening the stroke, or even by increasing the air feed, I could go on and on…

Re custom header
I'm not saying no one could produce a better header than ours.
But I challenge you to find that person & have it made for less.
And deliver equal or better quality, with equal or better performance.

TODA headers, including the sway, cost well above $2000, and that’s not even including a cat. You’re telling me, no-one can design a header, within that budget, which will outperform the low end of the TODA?

Your ignorant know it all attitude, is a joke. You do no justice to TODA.
How about, I give you a reality check. There are a number of exhaust engineers out there, who are capable of doing this. These guys often don’t get any recognition simply, because they do not represent a JDM brand. If you think, this is such a challenge; you have been sitting at your dyno for too long.

I’m not a fan of, ripping other people’s work. But I could walk into a custom shop, and have them make me a header, based off a SSR/Hytech/Toda design but modified to improve low end performance. And you know what? It would cost half the price, whilst performing better.

Don’t get me wrong, TODA headers are good, if you are after top end gains. But you will be foolish to think, a custom piece can not be designed, to be better in the low end. Before you repeat yourself, it’s not as much of a challenge as you think, if you know where to go.

At the end of the day you are, first salesman, second tuner, conning people into wasting money, is your job. I understand, I really do.
