I think that they look way better than the stock tips on my 90! They are good looking, the flat black stock tips...well the only nice thing I can say about them is they don't show the dirt much...LOL.
I think they look cool & on my black Z I think some shinny stuff would look great out back. I like them Z Factor! I have a Q, please
Those tips are really a muffler swap out, right? No can do on my car the mufflers are welded not clamped
Anyway,

Z Factor. I think the tips look very good, imho.
