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.

Well there are better options 43 years later with better ground clearance, better plug access, won't reduce turn radius with street sized tires, won't weaken the structural integrity of the front end, devalue the car and all without hacking up a nice vehicle.

Oh and I forgot to mention the torque boxes I needed to replace because they got cut up too to fit those headers.

I just wanted to inform the OP that there are other options to consider and enter my own experience "because fender well headers".
