you wont notice a difference...just like people on here were talking like they noticed a difference when you remove weatherstripping, which you dont. if you do, you need to check yourself into a hospital. anyways, im not saying theres not a reason or not right to do it, because im sure there is...i would just worry about a lot of other things first, like bigger turbo, forged internals, pulleys, cams, significant wieght reduction, cam gears, etc before i started making my car look like it was a victim of a bad insurance claim
