Stock STI downpipe <---need a pic

I just got my 04 STI about a week ago, I was under the car yesterday and noticed it looked like I have a really nice stainless steel downpipe. There is no marking on the downpipe but they are no cats and it looks to be about 2.75" or 3" Just wondering what the stock one looked like if it wasnt the one on my car.

Any after market exhaust would be smooth piping, while the oem down pipe is casted looking with tabs on it and bolted onto the car 3\4 the way up.

WEll I definatly have an aftermarket downpipe, pretty sure the up pipe is aftermarket too. I cant find any markings on it though. How many cats come on the car stock? I only have one on there right now. Thanks Guys

on the STI just two cats in the downpipe, none in the up-pipe, so theres no real reason to change the up-pipe like on the regular WRX but some people still do, and for what its worth I know of at least one guy here who passed Cali smog with a catless up pipe and a single cat down pipe
