I'm going to be buying a new DP since mine is leaking and i was just wondering if there are any on the market that already have an o2 bung/nut welded on so i have one less step and a trip to the muffler shop??

Figured i'd ask the guys in the Evo trenches before trusting google results, hah.

 

Are you running a Cat or a test pipe? If a test pipe, then you could have the bung welded onto the test pipe. My DC Sport one-piece DP, which eliminates the Cat, came with the bung already welded on it.

If you're going to have an O2 bung welded onto a DP, then locate it down near the Cat/TP oriented between 10 o'clock and 2 o'clock.

 

Yeah i was actually looking at the DC cat delete DP that comes with it welded on already. But right now i'm running an HKS tbe, with a high flow cat. Because Allegheny County, PA is an emissions ***** .

Was trying to see if there were any pre-welded bung for a normal DP. But it seems like only the test pipes have it.

 

what downpipe did you have that is leaking?

 

The turbo xs does aswell. I like the bends and quilty of the welds etc. It has a bellmouth type opening that is great when used with a stock style O2 housing. But can lead to problems with some turbo kits. I dont regret buying it but would rather have a Buschur personally.
