Hi,
I see there are some questions about our headers for the 370Z. Here are a few of the benifits of our headers:
1. Our headers are designed on Solidworks 3D cad software for an accurate equal length tube design.
2. Tube lengths are designed for a specific power range. Just making them long with no specific length in mind is not ideal.
3. Our headers are stepped from 1.75" to 1.875" for increased power and flow.
4. Tubing is 16 gauge mild steel or 304 stainless steel depending on order. We offer mild steel headers as a less expensive option, but have sold many of the stainless versions too.
5. We use REAL racing collectors, not cheap formed tube collectors. Collectors are desgned at a 15 degree merge angle for optimal flow and reduced turbulace.
6. Our 304 stainless headers have 304 stainless flanges. They are 100% 304 stainless
7. We have a lot of experience building headers. We build 20+ header sets a month for 20+ moldels of cars. We have been designing header, exhaust and intake systems since 2001.
8. We use JetHot ceramic coatings. Their ceramic coatings are far superior to genaric ceramic coatings that most header builders use.
We did our initial testing on a stock 370Z with everything else being stock. We welcome others to do dyno testing of their own and post their results.
I haven't seen any headers available for the 370Z that are equal length, tuned or use a merge collector. I feel confident that our design is the best available right now.
We are also working on a 1/2 wave length header that had an integrated 5" round ceramic core cat. Applications will be for the 350Z, 350Z HR, and 370Z.
