probably not perfectly accurate, because the string i used was a little bulky, and i didn't take a marker down with me, so i had to make wonky cuts to mark it. but, circumference of the exhaust pipes, right after the header junction, was approx 5.75" --> ~1.75" diameter. the headers are larger in diameter, and then they taper immediately before the exhaust junction. so, maybe my dealer was just not wanting to put them on....
