Nice, I did mine in about that time. The stock one is hard to get out...and I had the same issue on the catback, have to hold your mouth right.
This reminds me, I need to go back and check all my fasteners now. I picked up 2 tenths and 2 mph on my 1/4 with just this fyi.
Btw, roll the windows down and ease into the throttle like normal driving...the whistle is so diesel like...
