340 manifold vs TTI's which set-up?

if it is truly 100% performance you are after, then go for the tti's. the stock iron won't match it. if it is 50% performance and 50% the look of a 340 then the stock iron can't be touched. personally if it were a true high performance build the answer is the tti's, but if it is a fun peppy 318/340 clone then go with the iron. maintence and the duribility of the iron is also a good factor. face it tti's or any brand header will slowly rust. at least everyone i have had before has. just my 2 cents................
