Think there’s any concerns about having the wideband after the ball joint or should be good to go?

Making sure those ball flanges seal is key so you arent getting oxygen in from a poor seal and skewing your readings. Engine movement and vibrations can cause the leaks of course. The wideband isnt used by the computer of course but you still want to accurately know how you're running.

My buddy added Vibrant Turboflex 3" flex pipes on the s-curves of the stock exhaust behind the cats which should allow for compliance in the exhaust with engine movement and prevent the flanges from loosening/etc, along with allowing the bolts to tighten the seal even if the angle isnt perfect since it can flex back and forth a bit. I would recommend this to anyone doing longtubes to save yourself some hassle down the line.

The flex pipes are 6" long and 3" in diameter. Link and pics attached.

Sorry to restart and old post but will the car pass emissions with these cats? Will they throw an engine light if not tuned?

If your state (and yours might be close) to CA, I would not count on these to be compliant. I know CA's is the worst/more restrictive, but if you don't already know what the regulations of your state are, I'd look in that first. I know here, you can't modify the ECM/PCM in any way, unless there is a CARB-exemption. Again - I know CA's the worst, but I thought I heard more and more states are starting to shift their programs toward CA's program... Those state 49-state legality, but again - that's not always the entire picture.

Check stock fyi, G-Sport is re-branding their cats and there is a shortage (as with everything these days).

I ordered CSP 2" headers and cat delete pipes and mine order was shipped out with no issues. Mind you, I live in B.C. Canada

Does the passenger side header touch the aluminum cross member. I have the CSP headers and mine do touch.

Mine touch just barely at the same place
