Hey i was wonder from one of my other post.
What would be the best wat to Ground out an aftermarket exaust
And if Welding is involvd, would i need to Disconnect anything to Keep from frying out things like the ECU,O2 sensor, and other things like that

 

Generally all you need to do is run a simple ground wire from one of the exhaust flange bolts to the body of the car. Honestly it's not critical since even the OEM straps rarely last more then a year or so...

 

yeah but im trying to ground out my O2 sensor due to the fact that its all over the place.
I was directid to Ground it out
