Out of curiosity, for us with a DE engine, do we re-use cat-manifold bolts or use new hardware? The video floating around is for an HR so I'm wondering if this is a minor difference. My HFC didn't come with cat-mani bolts, and company said to re-use hardware. Wanted to verify if this is accurate before I get my car all apart and then need to hitch a ride to hardware store.

If your bolts/nuts are in good shape just re-use them.

What brand of impact tools are you guys using? I need to invest in some. I want to do my brakes next

Needs a lot of work and I mean a lot but I love it!
Does anyone know the size of the bolts hold the cat to the transmission?
