Does anyone know what the inner diameter of the SR header is, where the header meets the block and also where it meets the cat. The reason for this is because the inner diameters do not look any different from stock. I am using the search feature to see if i can find comparisons like that but have come up empty handed so far.

 

I DONT KNOW I WAS WONDERING THE SAME THING I'VE EMAILED THEM A TIM EOR TOO I WANTED TO KNOW HOW BIG THE COLLECTOR PIPE WAS. I'M GUESSING ITS 2.25 AND THE INDIVIDUAL PIPES FROM THE BLOCK ARE 2

BUT I DONT REALLY KNOW, GOOD LUCK smile.gif
