Headers and difference

[SRT_DSTRHOLC]

I already am going with TTI headers, but I have a question. Would anyone see a difference going from aftermarket 1 5/8 like a flowtech, summit, etc to another 1 5/8 like Doug? I know I might see little gain going to TTI because of the stepped design to 1 3/4, but is there really any gain between the after market headers or is it just pay more for fitting and ground clearance?

Fitting and gc. Also unless your motor is pumpin 550+ HP just opt for the digs and save a couple hundred bucks

True, I already have some headers and if its only GC then I dont really care until these start getting holes in them and getting flat.
