MUKAK

need them for a mock up project ( custom Exhaust ) i will be doing so the cheaper the better

dont need the mufflers, just the over the axle piping

i have a 06 Z06 so the piping is 3 inches, i dont know if the base piping of 2.5" would fit, does any1 know?

thanks

I would say its safe to assume the bends are identical. I have read about many folks who have upgraded from stock 2.5" to the Z06/ZR1 3" systems on base models and GS.
