I have not unfortunately. Went JB but I didn't want to wait as the exhaust shop was crowded.
I tried twice to install it myself but my cheap ratchets were all stripped. The bolts on the headers were torqued down high.
Already bought better tools and 6 point sockets. Will attempt a diy session again.
On the other hand I am tempted to visit Visworks JB and put it on a dyno and do a before and after
But no time to go over and I am not sure if they are free enough on weekends.
