Full length unequal length header for the GE8. This replaces the upper section and the lower section and gets rid of both cats. This gets rid of the factory donut flange and replaces it with a v band and a flex pipe. 
This will cause a CEL but that can be fixed with a defouler on the secondary o2 sensor. This keeps the egr system as well.
***for off-road use***
These are made to order and lead times very depending on how many orders I have in the queue.
