Long and short of the story, I have an m20 that I picked up awhile ago that I never got to install. I just picked up a 2006 vw gti a few months back and I have been tagged twice because of heavy foot. Am i wasting my time by installing this or should i just get an m27? Besides I think i am going to have to cut my grill to do this anyway, and I only want to do it once. Any help would be appreciated.
