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.

Install was smooth. The picture shows 4 parts for pipes. this comes as all one unit with one extesion pipe to the flange. I was happy to find this out. The tips are very nice and thick at ends. Start up is loud. Very low exhaust note.This exhaust is 7 out of 10 for loud sound. You can set quiet start if using remote start this will keep rpms lower when remote starting to warm up truck. Cabin noise is 3 out of ten not bad at all. On highway its always there. just buy
