I emailed BTG and asked if they were going to make a 2.5"/3.0" and was told they had no plans to produce a larger exhaust but they plan on working with the turbocharger itself in the near future? What that means I do not know? I would think if they are going to do any turbo upgrades it would include a larger exhaust,down pipe and CAT. This is what I am waiting for, a bolt on 2.5" turbo back single outlet exhaust. I do feel the BTG would work well with an off road stage I kit.[
