of those two Id say the silver one... Im also looking for a single pipe tip that looks like the stock one..
 
Sorry neither TBH.
The 6" x 4" of the LCR is by far the best looking one I've seen.
Or the same 6" x 4" one but slash cut aswell.

7.3", lol thats massive, did you see the pipe coming into it, its tiny.
