I am wondering what tips are these (see picture).

Thanks

 

Not sure on the tips, but really doubt you'd be able to fit those without a diffuser as big as his.

 

That's the Vorsteiner rear bumper....I looked for those same tip but couldn't find them...I went with Maxspeed tips they look the same...staggered outlet pipes with a diameter of 89mm...To better alrigh with my bumper I went to the muffler shop and got. 2.5 inch extension...I'll post pics once the car is out of the shop this coming week....
