Why does Borla advertise a 4" tip with the "Stinger" axel-back and FRPP ads list a 3.5" tip? I thought these were the same parts (made by Borla for Ford)?
I noticed the same thing (3.5" vs. 4") when I was preparing to purchase my Borla axle back by FRPP. As far as the axle backs go they too are the same (Borla vs. FRPP) and have the 4" tip.
