Lasse wankel header
Well since i made my first prototype steel header that made 7 hp more on my RotoTest comparing to stock log type manifold i had some problems contacting my Tig guru and header maker. He will not answering the phone, so i have decided to contact another company that shall build and weld my Renesis header. The plan is to launch the header to public in June if no more mishappens takes place! I will post data on my webpage that shall be up in a few weeks.

Ok! I know it,s already Saturday and no pic yet...but as soon as my friend is home to me with his camera he can upload it for me.
Yes there is a little deeper throatier tone not much but it's there!
I think when i measure the sound with a db meter 20 inch 45degree backwards the exhaust it was like 82-83dbA. That was with only the complete exhaustsystem (no header)

If you actually made 7 hp i would not post any pictures until you have a patent for it.Most headers now only get from 3 to 4 hp ,you never know who might be looking here and steal your design.

First i actully made on my Rototest 10-12 hp more with "my" Ferrita complete exhaust system minus header. The car went from high 6s 0-60 mph to 6.23s with exhaust system and Shell V-power 99 octane fuel and Motul oils. Then i dynoed with my steel header on same RotoTest hub unit and made +7 hp at 8000+ rpm. 0-60 mph went down to 5.86s. Of course i know this is not proof enough but when Peter G finally makes the first stainless header(hopefully in July) i will have proof with dyno curves and some photos. I have not driven the car since 7 weeks though i had a gearbox failure but next week i will also add an Interceptor X.
