glad to see it fits well on an XI! We had some issues with fitment during the beta testing with AR design, nice to see it fits perfect!

The factory bracket that mounts to the DP needed some slight "massaging" to get it to fit. Other then that no problems. Im using a Vibrant O2 sensor spacer on the post cat o2 sensor. So far no CEL. Initial drive car didnt feel as snappy but sounded great. After a few drive cycles the car began to wake up and feels strong. Pulls harder up top for sure! Hopefully I will be dynoing within the next week to see what type of power gains I made from my previous dyno with the JB3/AMS exhaust.

Below are some vids and pictures. I took some driving vids with my go pro. Yes the car is dirty, we just had a snow storm.


Revving and Driving video


Initial start with open downpipe only, no midpipe/muffler attached.




Pics.













In this pic I took the top covers off to disconnect the front o2 sensor from the main harness. I removed the Downpipe with the front o2 sensor still installed in it. You can probably remove the front o2 sensor while the DP is in the vehicle, or after you loosen the DP and position it in a different position, but this was pretty simple.

SOUNDS SICK!

Did you feel torque was gained throughout the powerband or just mostly hp?

It definitely has more power up top. Power doesnt seem to fall off as it did with the stock DP. As for TQ, feels similar, with the JB3 power always came on strong so its hard to tell.

Fitment was damn near perfect! Like I said, just that one bracket didnt line up perfect, but all I had to do was pry it slightly and it was perfect

I didnt order it from AR. I purchased it new from a user on the forums that decided not to install it.

Dynoing the car on the 22nd
