Dirty,
I have a few questions.
1. Do you make them for V8 non VV-TI?
2. Is there any change in performance? Not looking for 100 hp and flames from the tailpipe but is there anything you can report on. I'm getting that cute little rattle after 125,000 and I'd MUCH rather go this route than $2000 and the dealership and OEM if there is any performance upgrades to be had.
