Also, Are u going to use locking Header Bolt like Stage 8?
Curious is you will get any Fault Codes from the O2 sensors being moved?
Look forward to your feedback. Thinking about the same upgrade.
It will bolt up to a catback but it may require some cutting of the pipe to allow the y pipe and pipe to connect together. I didnt use the stage 8 bolts but if you order the kit i believe they come with it. I just used header bolts and they have been working leak free so far. I havent had a code come up yet and i extended my 02 wires by adding wire to the factory O2's. I really like the make of the headers and how the truck feels with them added. I still think there over priced but i rather pay for proven performance anytime.
