exhausting questions

[724wdcopper]

anyone out there have any experience with hedeman xstream headers? are they full length or shorties? guys at parts store can only look at the pictures, and that is a car header.

also, flowmaster, dynomax, ultraflow - which has the most mellow tone? was thinking flowmaster bigblock 70 series or similar. with a stock 1995 350, my truck is no race machine, and i don't want it to sound that way. have true duals now, but just the other day the drivers pipe rotted off just behind the muffler. not all the way, just a giant, spiral hole. sounds like a horrific exhaust leak ( i guess it is, really), but i cant stand it. because i work at night - 14 hour shifts - i havent cut it off yet, will do this weekend.

thinking of going with a 3" single instead of the 2.25 duals. i guess i just like to be different. i dont like the uneven exhaust pulse of the true duals, and a crossover looks like a pain in the butt with the t-case in the way. any opinions out there?

as for bolt on kits, i cant seem to find much in the way of 1972, but lots for late model stuff. my dad thinks that would be the way to go, a late model bolt on instead of exhaust shop. he owns a body shop, so welders, torches, lift, and other tools are at hand. anyone tackled a project like that?

thanks for your help!
