I put this on last night:

The ground wire isn't long enough to reach the new cannister, so for now it's kinda rigged to the long hanger coming off of the cannister...just wondering how much trouble I should go to to get it to the new muffler. What did those of you with custom setups do?

 

I don't recall re-connecting the ground wire. But it has been a while since we upgraded to the Borla.

 

It helps maintain a uniform ground across the whole chassis.
This, in turn, reduces the stress on the alternator (which, in turn, reduces the load on the motor) and suppresses odd PCM behaviour, ignition issues and radio interference.

 

the afterburners won't kick in properly without a good ground ...

I left mine loose, the only way to connect it to my custom would have been to extend it or run a new one

 

The Greddy SP2 doesn't have a mounting point for the ground strap, this is how I rigged mine.

so it basically doesn't do anything I'm tempting fate by not running mine anymore

 

And by that logic, neither does your spleen.

 

Ok, if we try and follow your weak analogy, then someone must have lost an alternator or worse a whole motor by not reconnecting that ground wire. Can you in fact show me some hard data (tech) that proves this thing actually does anything? To me it sounds like you are just spouting an aftermarket grounding kit's marketing line. Amazingly enough, my car starts, runs fine, and the radio works great.

Do you sell grounding kits? What's with the kool-aid drinking?

 

The thing is why would there be a grounding strap back there if it wasn't needed for whatever reason? It obviously has some sort of function. What that function is I don't know for sure, but my guess would be something to do with the O2 sensors.

 

I've got the same exhuast and didn't reconnect the ground. I've put about 5k miles on it with no noticable problems.

 

Well, I suppose your reading comprehension leaves something to be desired, so I'll first implore you to re-read my original post and compare it to you logic above.

No one will loose a motor or an alternator. The stress isn't nearly enough for that.
But what you will have is a non-uniform ground that will rob you of performance. How much is up to you.

There are english and reading classes at a local community college near you, no doubt.

 

not worth the time it took to write. Please drive through...

 

it could potentially cause an issue with the O2 sensors if you had a bad ground somewhere else, in general though it's not much to be concerned with. The OE exhaust gaskets are all metallic, so you'd essentially have to lose your grounding between the battery and the engine to have a problem ... and this would likely cause bigger issues

 

 

Perhaps it plays a role with corrosion?
