I dunno what the problem is since the light didnt show up right after the installation and before those 80 miles that were put on the HFCs.

Also every time i slow down i notice a weird hissing sound. I cant hear this with windows up, only down and at speeds below 30 mph.

So if anyone can address this problem i would really appreciate it. I personally think its faulty installation. I dunno help me out
Dont worry theres nothing wrong with your car. The CEL came on because of a cat deficiency code from the HFC. The car thinks your catalytic converters are shot. The hiss is normal too, just about everyone with exhaust has a decell hiss. Learn to love it because its from the car, not the exhaust.
