Thumbs up headers

don't go cheap, i just put on a set of hedman and i'm on my 3rd muffler shop to get the flanges right, i thought it was the shop at 1st, it wasn't, i put on a jet chip too, it really helped, the cheaper the header the louder, my flowmaster is really loud also, good luck, if i could do it over again i would have saved for the thourley headers, expensive but worth the non-headache, mines a 1994 f350 w/7.5 460, i love it

jet

i believe right around 250.00 at summitracing.com. make sure you talk to an intelligent salesman, they sent me the wrong headers twice, make sure to read all instructions, you mat need to remove battery wires the reapply, the jet chip really helped the fuel delivery

I put the Thorley's on my truck and what a difference in power. I haven't needed to rechip the truck either. I paid 680 at a speed shop locally summit sells them for 600 dollars.
