I have Hedman headers but not that good of vacuum on DS as you had. Not sure in having them installed 4.5" past collector in the header extension makes a large difference or not. Would be interested in checking how much vacuum they do have at idle and at high RPM but not sure how to downsize breather to a standard vacuum gauge.

Appreciate the offer on the breather. Will keep it in mind. Summit has one for $30 and I need some other stuff so will probably go that route.
