Yes, they fit. I bought from AliExpress for around $400. You need to get tips that have and ID of about 58mm/ OD of 60mm. I had to expand these as I bought tips 2mm too small, but easy to expand with a pipe expander.Do those fit the S3 exhaust? if so, where did you get them and how much?
You need to cut off the old oval tips.
I detailed the procedure here: http://www.audizine.com/forum/showt...EM-Rez-Del?p=11602570&viewfull=1#post11602570
I first went with the DC tips, but too large for my liking, so went for the smaller CF tips.
