ZZP Down Pipe

[GTPJIM]

I just received my ZZP 3" Catted DP and was wondering how difficult an install it is or should I take it to an exhaust shop?
Is the manifold flange easily accessable from underneath?

If the cat back bolts arent rusted away, it's pretty easy.

The rear manifold bolts are easy to reach with a few extensions.

I could have done mine myself, but I took it to my buddy's shop and gave him $30 to throw it on the lift and do it for me. The only issue he had is the one bolt on the catback side was slightly rounded, but he just used a "bolt out" and it came right off.
