I literally just finished installing these on my 2014 PI, that rear pipe was leaking oil at the connector, and EPP had a Tax Return discount... perfect timing. :-) I'm not sure yet how I like the VTA sounds, but I can always turn up the stereo.
Took about 2 hours, and to stop in the middle to go get some deep sockets - doh. YUGE shout out to BigMac - your pic's and writeup made this almost easy! So thanks a million for that!
