4.7L V8 Rear 02 Defouler/Spacer Options

[fulltimervexplorer]

So ive been doing alot of research before i receive the DT longtubes and ive talked to a ton of different people and everyone seems to have different defoulers/spacer options on there rear 02 sensors. What kind do you use and what types have you had no luck with. So far ive heard the J style, 2 from stacked from Jason at Burtman and also seen a 90 degree. Part numbers and were you bought yours would be much appreciated.

I was just wondering if you went ahead with the DT Longtubes? I am currently where you were too, wondering what spacer or defowler I should run. I bought J ones with interchangeable size openings so I'm not sure what to use.

I used something like this:

Not the same brand, but same size. I didn't stack them - only needed one per side.
