I'm in the market for headers and a y-pipe (ceramic coated of course) and I was leaning towards the heddman's, but as I was navigating through YearOne's site, I see that they still have the Flowtech Headers with Y-Pipe (ceramic coated) for $370. But it doesn't state what diameter the tubing is at any point in the system??

Does anybody know about the primary size and collector size of this system? Or what about the quality of Flowtech? I know next to diddly about them or their products.

 

Oh yeah....are they emissions legal as well? I need that garbage here in GA. It states that they are 49-State legal?....does that mean A.I.R. and stuff?

 

I dont know about their legality, but I believe that they are 1.5 primaries.

 

my flowtech shorties are 1.5" primaries.....i didnt get the ones with the y-pipe, but i believe it is 2.5 " in diameter. mine seem to fit quite well.

 

This post has a lot of relevant info for you:

Dustin,
So your still happy with 'em huh? Now since they're 1 1/2 primaries as opposed to 1 5/8, you don't notice any lag or loss of power up top do you? And just how loud is that noise? Annoying enough that you can hear it through the fire-wall?
