It makes the engine more raspy sounding, and it seems to make it rev a little better. Try removing it and putting in a K&N filter, you'll like it! Some guys claim they gain a little in the quarter mile from removing it too.
yeah, i took it off of mine and didn't really notice much. made the engine sound a little different. maybe the rev's got better...could just be my imagination too
My big bad mean 00 V6 Sounds cool up top with it gone. Can't tell if it help hp though, at least my car is a pound lighterm thats like .01 hp gain! Damn,I could take on any mustang now!
