Downpipe/Dump, 02/Wideband Bungs, 3" Exhaust Cutout *Need FAB Placement HELP*
Hey guys
Im kind of stumped on how I should go about doing this setup.
First off the car is an 88 Crx Si with a D16 motor
Im stumped on how I should run this setup, I dont know where to put everything in what order and what the laws of rules of making the best power are.
Check out this pic first
Its small but you get the idea, now heres my questions.
Im going to run a 3" downpipe into a mechanically operated 3" exhaust cutout. you can see in the pic how it is curved, i want 1 90 bend and then almost straight down about 10" into the cutout
Now as you can see my wastegate comes out just above the downpipe but it about 3.5" BEHIND it
I need to know where to make the wastegate dump enter the downpipe and if I am allowed to make it enter 2-3" above the cutout or if it has to enter BEFORE the 2 02 bungs
Someone please clarify that for me
Im just lost really on the fact if I can make the wastegate dump enter AFTER the 2 02 bungs or if one has to be ahead or if there any rules like that?
If it matters its OBD0, I should maybe also mention that Im going to have a full 2" exhaust being routed back from the downpipe
Let me know if you guys need anything else or pics or whatever

If I was you, I wouldn’t even bother with that. just let the WG be by it self, let it blow off underneath your car or something, unless your worried about emissions and stuff.

Even if your looking for 15-18psi and 300whp? or would it be more benefical to run it down at the bottom of the e-cut and the 02 bungs be at the top of the downpipe
Does it matter when the 02 bung and wastegat goes?
