Need help identifying part numbers for exhaust system bolts (1 Viewer)

[sonk76]

I've been struggling to find the OEM part numbers for the nuts and bolts that connect the mid pipes to the headers, and the mid-pipes to the cat-back portion of the exhaust.

I can't re-use any of the hardware that was there, so need to order new ones but can't figure out the part numbers. Any thoughts?

My understanding is that there would be:

6 bolts + 6 nuts (3 and 3 on each side) to connect mid-pipes to headers

and

4 bolts and 4 nuts (2 and 2 on each side) to connect mid-pipes to cat-back exhaust.

Any thoughts, ye wise men of mud?

Are you sticking with the factory headers?

If you are and cannot remove the hardware without destruction, then you will need:

(6) Studs for the exhaust manifold flange 90126‑10006
(6) Manifold to cat bolts 90179‑10070
(2) Header to cat gasket 90917‑06065

I assume you are doing the mid pipes and cat-back at the same time? If no hardware is included and it is all OEM spec, you need

(4) Nuts 94185‑61000
(4) Bolts 91515‑61035
(2) Cat to exhaust gaskets 90917‑06045
If you have O2 sensors provisions on the mid-pipes, then get new O2 sensor gaskets, hardware should be OK for re-use

Just finished the DT Cat Back install along with the headers on Monday, like it so far
