Size of stock downpipe?

[Wld87GN]

The weather was nice and I decided to get under the hood and take a closer look at what I have.

So after measuring the up pipe @ 3", I removed the turbo cover and measured the downpipe and it too measured 3". Is this stock?

Nope. Probably the Kirban replacement.

Your picture didn't show up. Is the downpipe a two or one piece?

Well it appears like it is one piece but I am not sure where it would come apart as two pieces. All I do know for sure is that it is big, outer diameter is sligtly laarger than 3"

Picture no worky. If you are measuring anywhere on the downpipe and getting over 2.5", it is an aftermarket pipe. The stocker was a 2.5"-ish two-piece design. There were two bolts with spring-looking deals connecting the actual downpipe to the elbow that was attached to the turbo. If there is a nice, wide-sweeping 3" pipe transitioning off of the flange that is bolted to the turbo, then you have any one of the numerous downpipes out there.

I wonder why you cant see it... I will attach it. See if this works?

Looks to be aftermarket.

If that is a 3" then the elbow is an aftermarket as well. There was an offering by a vender, don't remember who, that offered larger stock appearing elbow. I tried to find a pic but couldn't.

Might be a Bowling Green elbow and down pipe.
