I did it. Actually I did it, put it back on then took it off again. I wasn't sure how much louder it got so as the car was running I took off, listened then put it back on and it is definitely louder. Granted its just a sound thing, it doesnt do anything harmful and as for low-end torque I've not noticed any difference-or course Im not racing off of stop lights these days either. That butterfly flap doesn't open up until you hit 3000 rpms, which for me is around 85mph,when you have the tube attached. Because of this I thought that maybe my MPG might be affected but on a recent 500 mile roadtrip averaging 75 mph (not going over 3000 rpms) I got 32 MPG, so I figured I would just leave it off. Most of the guys that I've asked about this say it is there to keep the noise down, similar to the baffle that we all eventually take out. As for Conformity, heh yeah right.
