Ok, I have a problem. I'm about to cut the hole for my wastegate recirc tube. I'm tired of the obnoxious sound and the dirty engine bay.
Here's my downpipe:
My original plan was going to be inputting the recirc tube on the second bend where it turns under the oil pan. That way there is no 'turbulence' in the exhaust but I am short like 3" of pipe and don't have the time nor money to order another piece and wait for it to show up. But I do have enough to dump it right after that first weld on the second bend. Close to my original idea.
But the main question I have, is it best to recirc the wastegate above the O2 Housing for proper metering? or does it matter to dump it after? I figured if I did it above, the O2 sensor would meter not only the downpipe, but the wastegate gases as a whole. I know stock isn't this way either.
Idea's?
I could dump it here:
or like 6" lower, you can see the extra pipe next to the manifold.
