Another Header question

I at one time did run a set of Hooker fenderwell headers on a 67 383 Dart.
They really woke up the 383..Drawbacks were limited tire size as tall tires rubbed on tubes..the collector hit the brace on the body under the fenderwell and had to trim the brace, as for weaking the car I suppose it does any time you cut out a large chunk of metal it weakens sommething. However the biggest drawback is the fact that once you cut out those fenderwells its going to cost you big money to replace it back ..if you ever decide to.
Howwever they sure do look tough...Seriously if I had to do it again on a mostly street car I'd probally go under chassis.
