Default Turbo Tony DP What size bolts?

I just received my used turbo Tony down pipe, the flange is considerably thinner then the greddy flange. Due to the difference of thickness, I doubt I will be able to retain the old bolts. So my question is, what size, length, and thread pitch bolts will I need to install the turbo Tony down pipe?

I reused the same bolts I used on the Greddy down pipe. It should still fit unless the Greddy hardware is really that long.

i bought grade 10.9 when i installed my greddy kit, it wouldnt hurt to just take ur bolts to a hardware store, check the thread, i believe mine was 8mm 1.25, and just buy something like 35mm instead of 40,, or something along those lines

i wouldn't recommended reusing the stock hardware as it should have been upgraded from the start. You should go to a stud and nut combo. With that being said you will be fine if you want to reuse the stock stuff. The bolt holes that hold the downpipe to the exhaust housing on the turbo are straight through so they wont bottom out if the flange is thinner.
