These started as berk high flow cats then were hollowed out into basically test pipes. The reason was because the honeycombs inside were getting plugged up. They now are fully functional test pipes that I ran for quite sometime. Sound great, perform great and a plus is they will pass a visual inspection as having cats since thats what they look like. They have defoulers built in to prevent check engine lights and also have the wideband bungs. At one point while running a nismo y pipe it caused some stress on them so some hairline cracking occured on the braces that I had welded as precaution. They are what they are and Im Sure would make someone very happy.

They started off as 500 dollar high flow cats
