The only thing you have to make sure is that when you are buying this spare, that you have a M4 grub screw handy as this kit does not come with it.This is pretty straight forward - keeps your muffler in place even when bouncing around in the track. I would have given it 5 star but the fact that it doesn't come with a grub screw or M4 screws at the bottoms gets this fair review.
