APR's 2-Piece Design Explained: As is true with all machined parts, it's impossible to make all parts the same. In the case of the turbo muffler housing, the distance between the bottom and top of the muffler's housing will vary from turbo to turbo. The acceptable measurement range is known as a tolerance. The nominal distance between the top and bottom of the turbo muffler's mounting points is roughly 51 mm. The tolerance on this part can be as loose as +/- .5mm or more.
Fits: Audi S3, VW Golf R/GTI (MK7), Porsche Macan. Confirm fitment with us before ordering.
