UR o2 downpipe/ Cobb stage 2

[NicksRRra]

Has anyone run the newer ultimate racing o2 downpipe with cobb stage 2? Im not sure if its a safe decision, i plan on upgrading the stock turbo later and would look to know if anyone had any experience with the combination of that downpipe with the stage 2 tune. I already emailed cobb about this, just waiting on a reply from them to confirm if its okay.

Do you mean the UR long downpipe? If so, that is what I have along with stage 2. No issues. I have the rest of the UR turbo-back too. HFC and mini-muffler.
