i just had my exhaust installed, and took a look under the car, i found this wire dangling....i believe this just bolts onto the exhaust bolts, am i right?

 

You are correct. This was originally attached to one of the bolts holding the mid-pipe and the muffler togeather.

 

yep, just a ground.

man...that's one fugly exhaust...!

 

yes that's a ground and it's supposed to be attatched to the hole on the exhaust right above it. There should have been a bolt and some nuts that came with the exhaust to bolt that ground wire on, that's how it was on the HKS i previously installed.
-GP-

 

I would find some way of grounding that to your exhaust, it will help your 02 sensors monitor more efficiently

 

yep, HKS Ti exhausts are fulgy as hell..
