For $475 shipped, you can buy an entire Top Speed X-Pipe and cut the front sections off to make test pipes. This option has been available for almost a year. Band clamps cost about $10 each.
I am using the entire Top Speed X-Pipe. Back when I bought, they did not have a resonator version, so I added resonators. I think they sell one now. Delete all the cats and you gain more power (though the two primary cats are the more restrictive of the four).
I can just modify the OEM ones, but then again, not modifying them gives me the option to switch around come inspection time. I do not have my secondary cats, but I do have new resonators where the OEM ones were. I am ready to go full catless and get the tune, but for $495, I'm a bit wishy on it. I hope TMS comes back out with theirs ASAP.
