Well Over the weekend I decided to go ahead and just build my own down pipe. I had ordered one from a forum member and according to VRSF website and last 7 of my vin entered my 2015 supposedly took a 3.5" downpipe according to them. Well after receiving the down pipe from the member I quickly learned that mine was a 4" and was told this was true by another friend from the forum cause my car is EWG. I uninstalled my stock cat and downpipe and realized that it wasn't going to work. So I put everything back together, which the whole job taking off and putting back on took me all of 1 hour.
So I sold that downpipe to another forum member and decided on building my own.
Cost me about $175 in material (All Stainless) and after we had the stock downpipe off it took us about 6 hours to build a jig, weld everything and re install the whole exhaust system. Which I don't feel is to bad.
I didn't get a pic of our jig but I have a pic of the finished downpipe. Im leaving work now so if the pics didn't post I will post them when I get home!
