About Kooks Green Cats!
Kooks now offers mid pipes with what they call Green catalytic converters. Normally when you install headers, you need to get a tune because the new high flow cats flow differently, and create check engine codes. The codes will pretty much certainly appear without a tune. These new green cats from Kooks use a special design that still flows at a very high level, but also does not throw codes for the vast majority of customers. In the testing thus far, 98% of customers did not get a check engine lights with the stock tune.
This does not effect the fact that long tube header setups are sold for off road racing use only. Any time you remove functioning factory cataytic converters from a car, you are breaking emissions laws.
