/sigh people said the exact same thing about my obx header i had on my mk1 focus, not a single tiny spot even after 4 yrs, same with the one on my 07 zx4st focus, which i bought used and wrapped, rocked it for 3 yrs and sold it and looked the same as when i bought, was completely 304 ss. yet the mbrp i had on my Fost (t409) looked like it was underwater for a century after 6 months, and the muffler actually broke internally... so without having direct knowledge of this particular piece, your comment is kinda invalid. not trying to be a jerk, just sayin
