Which exhaust

[vorstang]

Hi all, I have a 2010 with a Kenne Bell 2.8, it made 705 hp. 622 tq, it has OBX long tubes and x pipe. I was curious which exhaust headers and x pipe would be best? Can I run a catted x pipe or should I run a off road pipe. I would like to run cats but I hear horror stories about them plugging up under high boosted applications.
Thanks for the help

I may be wrong, but at your HP level you may be best to go catless. It seems there aren't any cats made to survive the upper HP level cars for very long. You may be pushing that threshold.
