3" Downpipe with Divorced Wastegate (DDP) -- 369$

Always worth the extra coin to skip the cheap Chinese made ebay products

The purpose of divorced pipe is it gets the turbulent air released from the waste gate out of the main flow which helps improve exhaust flow.
If your worried about legalities they will recirculate the divorced flow back into the main pipe as well.

Its just a pipe though. I don't get why I would spend more on the brand name. What is the difference? Please just give me an explanation so I understand. Its a pipe with no moving parts to me. A long as its thick enough and made if the right metal, I would even put a mario brother warp tube down there.

Its the good old "you get what you pay for" theory. Which is why I don't like much of what is sold on ebay. The pipe looks good in the picture but without seeing the welds and quality of metal, you don't know what is will look like down the road. I don't know how the tanabe here is:

But I have some suspension braces of theirs on my celica that are pretty nice and they are made in japan.
