Cat vs. hollowed cat vs. testpipe
I used to run a "gutted cat" in my Eclipse SDS race car and replaced it with a set of test pipes. I seen a slight hp increase but that might have been due to weather conditions etc...
If its a DD and its a strict state with EPA laws just get a highflow cat and test pipe, if not just get a test pipe would be my thought.
