ATP high flow full 3″ O2 housing for Evo 4/5/6/8/9. This design deletes the factory donut gasket to eliminate the 2.5″ restriction between most O2 housings and downpipes and creates a true 3″ all the way through.
*Discontinued*
We are sorry, ATP no longer manufactures this housing and we have none remaining in stock

Vehicle Fitment:
1996-2006 Evolution IV V VI VII VIII IX
More Info:
Works fantastically well with large stock location turbos with large turbine wheels. This eliminates one of the biggest bottlenecks in the Evo exhaust system.
Also, the 02 bung is strategically located away from the direct exit of the turbine wheel to avoid additional restriction and turbulence.
Install Notes:
It is advised to use a mating downpipe that has an integrated flex bellow after deleting the donut gasket. This will ensure vibrations and engine movement during driving is properly absorbed to avoid stress damage to other parts of your exhaust system.
