Well all I can say is I hope you have a big cubic inch motor. If your on an regular 346 then it will be pointless to have those on there, it will proably hurt performance. Or you can go with the 1 7/8 if you just have to have bigger but I wouldn't recommend using the 1 7/8 unless your over 400 cubes.

Those would be **** if fit and finish was excellent.

Don't listen to those who say it will "hurt" performance. They would obviously be for the larger CI guys looking for the best exhaust flow possible, and those would be the TICKET.

yea, we own a fab shop tht builds sheetmetal intakes and exhaust systems, weve done some turbo manifolds for hondas and whatnot, but no n/a headers, our supplyer that we get our stuff from sells the oval tubing thats two inches thick and has the same flow of a 4 1/2 inch pipe, i cant believe that kooks are that cheap, i thought theyre regular headers were more than tht. neone got links?
