I've noticed a lot of support for the off road Y on this forum. How much HP can a Silverado take with a good set of LT Headers and single 3" all the way out? Are there any reasons/ advantages to running the off road Y compared to running 2.5"/3" true duals? (with H or X pipe). I was pretty set on duals, but with Forced Induction being far down the road it seems I might be able to do fine with the ORY until I get into the FI realm...
