I have two different downpipes! I ordered a Mostly Mazda Downpipe, but overly anxious and couldn't wait and got a SR Motorsports one instead because he had it in stock. I waited about 2 1/2 weeks for the Mostly Mazda one to come in, but ended up putting on the SR Motorsport one instead.
I ordered all the replacement turbo exhaust manifold bolts and gaskets from Mazda Competition since I knew they would all come out anyways. I would highly suggest ordering these items if you are going to change your downpipe anyways. Preventive maintence should never be over looked no matter how anxious you are.
The performance, looks and fitment seemed to be the same but Ray offered better customer service and had it in stock.
