Should I use under chassis or fender well,im concerned about tire issues with fender well,ive never ran them I would appreciate some advice from someone with experience with both or either,thanks
I have chassis headers on my build ('67 Dart bracket car) and am happy with them. Fitment was very nice (TTI) and haven't had any issues to this point. I imagine the chassis style are the most common as I haven't seen many fender well ones. Although I do have them for my '65 Dart. Good luck!
I see no reason for fender well headers unless the big TTI tubes can not handle the intended output of the engine.
In other words, there a restriction. The TTI tubes are generous in size. Excellent power should be able to be made from them.
Also realize that hooker and headman headers under chassis header usually have the 7 and 8 tube go out thru the inner fender...the TTi are all under chassis..
