1 5/8 headers

Currently have Doug’s D453 headers on a 408. I feel they maybe a tad small but don’t know if it’s worth spending the $$ for bigger tubes and I’d rather not cut the inner fenders.

Same boat, 410, TF heads w/Dougs. 3250lbs +/- w/driver 11.44@114 in aero akin to a barn door. Could use a single plane, more cam, more converter, more headers etc etc. Got what I got, no roll bar to run at strict tracks so what’s the point in my case. Fun to contemplate don’t get me wrong!
