I got some feedback. They look Ghetto. Seriously, you're just slamming them inside of the stock ones w/ a couple of set screws hoping to hold it??, not even replaceing the stock ones (which I opened this post going how the heck are they suggesting you get the welded on ones off, then I see this jury rig).
Its going to look like $hit on the car too, because if you look at it (and you dont have to do it very closely) you'll see its a tip inside of a tip.
This being my most curious part of this (although I dont know why i give a $hit, it looks so bad I would never do it), what happens from heat and cooling (expansion and contraction) if these are just pushed in there?? They are going to get lose in a short period and fall right out (if you are doing this using an interferance fit or press like pressure and some set screws). The set screws will get lose, I'm sure of it.. over a very short period of time. Try them on your own car and see.
The one good thing I can say about this, is if my assumptions are correct, you'll be back to stock looking tips after a few miles, whether you like it or not
Enjoy the feedback... brought to you by none other then....
