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.
