I'm looking around for an exhaust pipe and decided to check the wiki about performance exhausts. I noticed that the technigas is for high revs but saw nothing about the mid range. Then I saw the estriol mid-range until pretty high. I want the estriol more cause of the powerband but should I just get a technigas next or the estriol?
any one own a technigas? how does it run on an a55?
does it have a restrictor or should i bend the header for the estriol and run that?
