Its Sunday memorial day weekend but I wanted to reply to you post.
We do have dyno sheets for the header and center section system and I will post those up for you on Tuesday when I get back to the shop.
All of our systems are tested on our in house 4wd dyno chassis test cell.It is one of less than 5 units in the western usa. It is also used by alot of the oem manufactures.
Our systems do a make a considerable gain in power with our without software.
The header and cat system is developed and proven in World Challenge GT competition over the years and the same design we use on our race winning World Challenge GT3 Cup cars. It is also fully homologated by the series.
There are absolutely no check engine lights
with our system.
While I cant speak to other systems on the market and there performance or reliability. I can tell you we have been selling our systems for many years and have had great results both on and off the track.
All the system are hand made in Ca using Aerospace grade T304 stainless steel, are precision tig welded to AWM aerospace specifications. All flanges are laser cut and CNC'd.
We only recommend doing the header combination with the center section and leaving the stock mufflers as removing the stock mufflers has proven to make the cars loose power.
Every car we do at GMG gets a before and after dyno so you know exactly what your car makes as each car is different.
If you have any other questions please do not hesitate to contact me directly I am happy to answer any questions you may have.
If you find yourself in the are please feel free to stop by the shop and I would be happy to show you what we do and give you a tour of the performance and racing departments.
Here are is link to the header system.
