Just need a little info please, I want to install the Viper Street Cat-Back Exhaust on my 04. I did a search and have been reading about the sensors throwing a code on some cars and others are fine? One of my questions is from what I can see in picture of setup I’m not going to be dealing with any sensors? The other thing I will be installing these myself and it looks like the hardest part about it would be the two front bolts to get the sill off? My other concern is would I have to reprogram anything by putting this system on? Any info would be great.
