yes well they are a $500.00 pipe so hard to say good bad or indifferent, certainlyone of the cheaper ones out there but the sound from those pipes in my opionion is one of the best on these bikes, i would weld them as well. Also as a heads up, keep an eye on the area just behind the collar where they attache to the headers but under the pipe out of site, when the rivets come loose the baffle inside will actually splice a whole in the pipe (on the seam) by vibrating so much, ask me how i know this! Another weld.
