    Question about exhaust rusting....

    Has anyone ever heard of tying in with a breaded wire or sorts from the exhaust to the body of the car to aid in the slowing down or almost no rust on the exhaust pipe?

    I heard that is maybe what the cop cars have done in the years past to aid in this problem from a few people. Is this an old wives' tale or is there truth here and we could all use this knowledge to better our cars.

    TIA

        If you can powder coat the inside of the pipe...
        stainless is the way to go.
        wat?

          It used to be you could by a kit to send a small electronic charge through the whole car to prevent rust. I can't say if it worked or not, but since your whole car is grounded, I don't see it being viable. Just go stainless.

            this question was in ponder, I heard about it and thought I would ask you guys and maybe stir up something new. I had my exhaust done finally about three weeks ago!! WOOT

                Explain, please? In all my years (over 26 at this point) of working on cars, I've never heard the term bonded in reference to a car. My old MGB referred to it as earth, instead of ground, but never bonded. I'm assuming you're talking about the fact that it never actually grounds to earth, just back to the battery.

                I don't think a car is considered a bonded system. As a telecom installer, everything I built in a switching environment had to be bonded. Bonding equalizes the electrical potential in a building, so you don't get shocked if you touch two different pieces of metal with different potentials (for telecom, it also protected against lightning by carrying the charge to earth instead of to the equipment). In order for a system to be bonded, you need a hot leg, an earth (or ground) leg and then a neutral leg.

                    Having a battery "ground", and being grounded are two very different things, as you've already pointed out.

                    Layman toss around terms quite freely, as I'm sure you're well aware.

                    Car chassis's are the ground for the DC circuit of the cars electrical system. They are not grounded.

                      I call semantics!

                      I see what you're saying. I should have said that since the entire car was already part of the vehicles electrical circuit... blah blah blah.

                      And congrats on almost 1000 posts!
