Magnaflow 15479
Got the Magnaflow intermediate pipes in the mail today, looks like a direct ship from them. Only issue is there are no directions so I have no torque specs or bolts for the connections to the stock manifolds or for the clamps for the connections to the x-pipe.
Anybody have the specs or know the sizes of the bolts needed, or did you reuse the factory bolts?

The one I bought three years ago had a different part number of LP489123 that was supposed to fit my C5, the manifold ends were 0.600" too close together so they couldn't match up to the exhaust manifold. Someone at the warehouse measured another new set and they too had the narrow dimension so everything was returned. It's possible the design was changed since then but neither part number shows up on their website search function. I would measure the distance between the inlet pipe center lines and call the factory to check if they are close.
