Great quality and fast shipping
The quality is top notch, you can feel the performance difference and hear it too. I wish the adapter flange was included but glad its offered.

It's all good so far
I placed my order on the 4th of the month and received the downpipe on the 7th. The shipping was not only free but it was shipped within a decent amount of time. I've only heard good things so far about the Tsudo downpipe and I know people with it but I'm excited and can't wait to get it installed and tuned. So far my experience has been great.

Great fit and quality. No boost creep or over boost. Get an adapter from dp to stock exhaust 2.5" piping from rally sport. Turn all like 11 codes off for the second 02 sensor for the protune. Cobb maps won't work on a catless dp. I only have intake and dp and the tune to bring me to 291hp on the dyno.

Question asked: I see in one picture that the O2 bung near the bell mouth is in place, then in other pictures it is not. Does this product come with the second O2 bung welded in place? The one for the wideband.

Sorry for confusion. It comes with the Bung. The other picture is just to show how it sit while installed. We did not have one for the bellmouth, so we just used the divorce. What you see in the first picture is what you are getting. Again sorry for the confusion.
