Default ERZ catted dp opinions

I havent been able to find too many reviews on this DP. Im mainly looking at it because of its low price point. Does anyone here have one? Could you comment on its build quality and fitment?

Just got the down pipe in yesterday. Its an OK piece, i am working on installing it now. Welds are nice but there is a lip on the inside where the cat meets the bell mouth which i dont like, also the 2 hole flange at the very end is a little bit shifted by say a millimeter to the side so its not perfectly centered. Im starting to think that i should have gotten the helix.

Any chance you might be able to upload pictures? I've been considering this downpipe but haven't found a single review of the catted version anywhere.

I'd specifically love to see pictures of the aforementioned imperfections.

Ill see if i can get myself to do it, i hate uploading pics The thing that bothers me the most is the lip on the inside where the cat meets the bell mouth, it looks like it would disrupt the flow a bit, could you feel the difference if it wasnt their? Probably not, but hey its still their and it bothers me

Just got done installing it. Installing this thing is poop. I had some issues that were a PITA, i even had to go to the hardware store and buy a map gas/oxy torch to cut some stuff to make it fit. IMO buy a helix catted. Going to go drive it now after i flash new map. More info to come.
