I have a set of cheap Blackjack headers I bought 30 yrs ago on another Challenger of mine....small block and do not go under the steering...Maybe I'll steal those..look at the pics of the headers Summit currently sells if the pic is accurate no way the steering goes thru it.....unless all 3 of those tubes go under.....and this much worse than just one....
