I just received my ERZ performance downpipe. I have read good things about the company and their products over at wrx club forums. I bought the downpipe on Ebay and will install the part when my cat-delete pipe and cat-back come in. Here are some pics, welds look good, real nice piece. Price shipped was about $120. Good alternate for those that want a decent downpipe while saving a little money. 3 inch piping/stainless steel.

 

I got a Megan Racing Down Pipe off of eBay for $80 shipped. Looks about the same as that one except mine came with a flex section.
