I did speak with TTI few days ago. Woman I spoke said that TTI has never verified fitment but has sold headers to quite a few folks running the 240 heads and have yet to hear of any fitment issues. I know a couple folks have said TTI headers will work with the 240's, just wanted to verify...
I had asked that question on some of these trick flow threads before I bought the 240s and never got an answer from anyone. I had already modified my 2" tti to work with a B anyway.
