When I first bought the labree I had it put on my 96 na. It was taken off when I sold the na and its now on my 93 tt. On the na it was like a german tank and every little thing vibrated in the low rpm's. When Bernie moved it to my tt all the noise issues in the low rpm's dissappeared. I'd def recommend leaving the resi's out especially if you profile is correct and you don't have down or test pipes like me.
