What size headers
New to the group & first post. I’m running a DCI 5 combo, the guy that build my Taj Mahal intake also spec’d my headers. The trq numbers were a good bit lower than my previous build & thinking it’s a combination of huge plenum & too big of header tubes 2 1/4 to 2 3/8 5” collector. Anyone else running tubes this big on 1050-1100 hp range. My dad’s combo has 2 1/8 to 2 1/4 w/4” collector, smaller intake plenum as well & made roughly 80 ft lbs more trq.
