Quote: You would be better off to use a vac pump on the street... with a exhaust system it would have to be a VERY low restriction to allow a header vac to work
2" tti's w/3" tti x-pipe system and ultra flow mufflers.
I have the same exhaust set-up and have the evac kit sitting on the shelf, but I am very scared to try it!
All I can say is try it, if it fails cap off the nipple in the headers with a pipe cap
