vivanov1, naz24 is right. they are tips and they have a hole in the bottom for the slanted pipe. I bought a set like them and did not really like the look. I also found they caused part of the exhaust to be redirected at the base of the bumper leaving carbon residue. Furthermore they were still quite loose even after doing up as tight as possible as they only rely on a worm drive clamp to hold them in position.

The 4.6is tips look great but will set you back a fair bit by the time you have a y-pipe installed and the tips welded on. I had a local exhaust specialist cut off the old tips and weld on some stainless AMG oval "look a like" type dual pipes and I think it looks awesome. I would post but copped a lot of flak for my last posting so not that interested in getting others opinions on my exhaust - My advice would be do what you like, that is what matters. Cutting off the old slanted tips and going with a weld on option would be my advice.
