Good quality product, the "CEL fix" doesnt work though. The 90 degree defouler makes your 02 sensor read lean. Also, the flange for the catback is flat and will require fabrication to make it work with Exhaust donut flanges found on most stock and aftermarket catbacks.
Also, the ID of the cat is 2.5" even though the website says 2.25"

I had an issue at first but the customer support responded pretty fast and was able to update me on what was happening
