Finally got the downpipe installed!
I had my dealer install my Sxthelement catless downpipe while it was in for an oil change last week.
The improvement in exhaust note is worth it all by itself. The sound is much deeper and just a hair louder. I won't be doing any additional work to the exhaust now.
The modest bump in power is noticeable. Also, after a week no OBD errors have reared their ugly head.
