Pretty bold statement made there.

 

I have no qualms about making such a statement. I have seen dynos on this very forum of that J's setup with zero to countless supporting mods and the gains hardly justify the price compared to some other offerings. But how much can one expect from a header that is paired and lengthed like the OEM piece only with larger diameter piping. Sure is shiny though...

 

So how much power does the Hytech make? Do you have any direct comparisons with any other header on the market? How much does the header cost?

 

The header is about 1400, I believe this is similar in price to the J's. The hytech header version I am running has the secondaries taking up part of the OEM cat's location (eliminating the cat). I will try to dig up the pre cam dyno, but before my Jenvy setup running basically just the Hytech header setup setup and cams we were making over 260hp on a Dynopak. My baseline was 237. The biggest issue with 99.99% of the headers is that the primaries and secondaries are always too short, not to mention the pairing. The Hytech addresses all of these issues. If you look at my torque curve the header itself is a major factor in its shape. What needs to be understood is you cannot look at each component as a given power increase. Just like your body an engine is a system and every component, much like your organs. Every component must work together for peak efficiency (health). Bolting on a catalog of parts that look good then hitting the dyno for a tune is not how you get there. Everything in the system must be carefully optimized for maximum gains.

 

How hard was this to install? Did you employ a stubby testpipe or just have a custom exhaust made to mate up with the header?

 

Mine is a slip fit with a T1R 70. Since these headers are custom, you can order it with a stock flange to any normal cat back or leave it slip fit. If you order it for an OEM exhaust it will bolt to any cat back for an S2000, just the headers last merge will basically be where the cat was. Basically, the header is the length of any normal header + cat or test pipe.

Honestly, pairing does little but adjust your power band. If you want a header to work there are only two components that truly matter: merge collector and making the tubes as long as possible before the final merge. Seriously, pipe diameter means VERY little. The J's likely makes more power then most JDM headers, however the design is still flawed because the primaries are shorter then they need to be for this engine in particular. My final merge does not occur until about mid way into where the cat would be.
Simply installing a test pipe will not equate to this as my primaries come all the way to floor of the car and my secondaries start at the transmission. Long tubes + amazing merge collector = horsepower.

 

It's still apples and oranges. Your Hytech header is ending at the OEM exhaust point and the J's header ends where the cat is. I don't see how you can compare the 2. The only similar comparison would be to get a test pipe with the J's header and see how that measures up to your Hytech one. Also it's not worth it in Cali to not run without a catalytic converter the tickets for getting caught are just nuts.

 

Hytech will be more then willing to build you a custom exhaust with a cat that will function with a proper header.
