Twin turbo downpipe options
Twin turbo downpipe options I'm in the middle of putting twin turbonetics 76's in my T/A. They sit behind the headlights.The setup I have has a 3" elbow coming out of each turbo, then they merge into a 4" single pipe. It is supposed to exit between the motor and the k member on the passenger side. It must have been designed around the Spohn solid mounts, cause it won't fit between my BMR k member and motor....I don't really have alot of options since it's a truck manifold setup...I thought of running the downpipes out in front of the front wheels but I'm not sure it will pass PA. inspection that way.
-Should the downpipes merge to monitor the AFR?... (My BS3 only has one wideband)
-Is 4" too restrictive for 2 76mm turbos anyway?...
-Would dual 3.5" pipes help or 3" for that matter?...
Any pics or help would be appreciated!

What size comes off turbos? I think your best bet would be to swap to a bmr turbo kmember and run a DP back off each one. You could do a cutout in each one and then merge into your exhaust. I'm guessing you'd need your BS3 reworked for dual widebands as well.
3 inch off the turbos. I won't be running the exhaust all the way back. I'm trying to make it work with the K member I have..
What's the difference if I only have one wideband in a merge pipe? Monitoring both sides would be nice, but on single setups most guys only have one wideband monitoring both sides
