Tti headers or not?

Their 2" dyno headers with a 3.5 " collector but when I put my stalls on they matched the dyno headers and made 2 more ft lb of tourque but since my car was totaled back in October I need new headers and the only ones I'm finding that are worth anything is either the tti headers which are 2 1/8 or a semi fenderwells header by bobby mazolini or I build them myself I'm just wanting to know how much success people are having with the tti or even the semi fenderwells headers
