Sharing what the initial unboxing of eBay Maximizer "DT Knock-Offs" look like.
These: Maximizer Long Tube Exhaust Header For 2009-12 Chevrolet Colorado GMC Canyon | eBay "Maximizer Long Tube Exhaust Header For 2009-12 Chevrolet Colorado GMC Canyon"

Was actually expecting more of a brushed finish as opposed to the polished finish.

Hopefully the fitment is reasonable, might have complexity as mating to a LSX B15 6.2 Swapped.
The LSX B15 has extra head bolts that can interfere with the mounting plates/manifolds.

Probably should do a before sound video and then an after.....

Anything else you guys interested in seeing, besides the smoken tire video that not gonna happen ;)
Truck is ~550+ rwhp.

What does the flange inside look like. Is the tube have no seal to the flange?
Seller suggested similar, response was thought that was a bit irrational type of a inquiry as why would the fabrication include full weld beads on 5 of the 8 interfaces and leave 3 partially welded.

With that said, the internal interfaces are ground down as can be seen in some of the original post images above, close inspection the interface can be seen and concerned under temperature cycles over time there is a chance of the joint separating and becoming a leak....

Seems preventative action is to complete the welds to be consistent with the other 5 header tube to manifold flange joints.

Are you going to connect them to your stock y-pipe or will you use an aftermarket 3' SS y-pipe and full exhaust?

Did you beef up the 4L60e or go with 4L80e?

Did you replace your drive shaft and the 10 bolt for a 12 bolt?

Yep, cuz started with a V8 LH9, so works.

RPM 4L65E Level 6, or rated at ~600rwhp.. on 3rd transmission.

Nope, again, cuz started with a V8, kinda plug and play "Kinda"
The Rear End is now starting to feel looser than was 20k miles eariler for sure. The 1st to 2nd shift hits pretty hard.
