I'm repairing the body shell of my '70 Barracuda and adding stiffeners where necessary, which seems a good time to plan for headers and big pipes. Don't want front inner fender bracing to get in the way, and need room underneath for 3" pipes.

I haven't seen many photos of headers on e-bodies. Search does show Doug Thorley headers are the top pick.

Love to replicate the header 'ping-pingping-ping' idle sound from a solid roller cam.

Are headers no making much difference? Too much warping and exhaust leaks? Not enough room?
