Seeking Exhaust Advice

The orginal poster wants info on fenderwell headers. Why try to change his mind instead of answering his question? Fenderwell headers were all that were available in 1975 when I installed mine. Personally, I wasn't trying to copy a gasser. If one prefers TTI and Dougs that is fantastic, but I still say you can't beat access and convenience with fenderwells, plus the bends in the pipes are not as severe which may or may not increase performance potential.
