I tried to save a few bucks and bought Chinese downpipes. I've had good luck with my Chinese chargepipe, so I rolled the dice. The fitment wasn't good. I used the BAH method and have them fitting now without any contact on the subframe, etc. The worst was clearing a bolt on the engine for the inside downpipe. I had to pound the heck out of that one. The picture looks a million times worse than it really is, though. If they don't end up working for me I'll shell out for some VRSF pipes. I have their inlets and 7" HD FMIC, and have been happy with their fitment.
Like I said, I'm rolling with them and expect them to perform fine, but I'm posting this here as both a cautionary tale and to take any lumps y'all might want to dish out.
*Edit: I'm not worried about the welds at all. They're solid as. Even though parts look folded and creased, it's smooth inside. The pipes are real stainless steel too, as confirmed by a magnet.
