But not high flow. They allow a little better flow than the original converters, but not much more. They do sound better though. If I can get true duals on my car, they may work even better and the y pipe may be the main issue I'm having. Installation was a cake walk. Getting the old ones off was a pain, but these went on very easily. Would have been better if they matched up to the OE air injection without modification, but that's not a big deal.

I know, 4 5 star ratings and an overall 4. Doesn't seem to make sense, but it does to me. Outstanding quality of construction, easy install, great sound. HOWEVERif you order #15713 and are expecting an X pipe you will be disappointed as I am. The website description in the drop down still lists it, and it is not included.
