This is before the new wheels and tires. The rack was temporarily removed, as well. There is more to come.
Before installing the custom catback. The sound that makes you cringe.
After installing my custom 2" Stainless mandrel bent catback exhaust with the Hotshot header and a SE-R cat with the O2 sensor relocated behind it. No more CEL!
This is what I installed and removed. There's quite a difference.
