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.

Don't expect a true cat back. You'll still be stuck with the tiny factory y-pipe. All you get is a muffler and tail pipe. That being said, my Xterra sounds great and I can feel the improved hp when I stomp on it. Combined with my K&N intake, it's a great pair!
