Does a muffle delete cause Check Engine Light?
Yep, that's what happened, up to the LEOs discretion. I think all the Covid street racing last year caused a sea change in how they approach it. I'd say starting around July here in CA, we saw them getting a lot more aggressive with referees.
It's interesting, it can pass CARB requirements, but apparently if it breaks local sound laws, that's where they can hit you as well. I think it's 95DB at X number of feet away. Which is actually NOT loud at all. Most modified exhausts are much louder than that. Which goes to the next point, if it's been modified and hasn't been CARB approved OR is louder than allowed.. it's a fine and a fix (or they impound the car). If you lay off the exhaust around residential areas and definitely next to cops, you might be OK. If you get hit, you might be able to replace the midpipe and be OK. The Fsport isn't THAT loud in of itself.
Case in point, Seal Beach, CA is cracking down hard, so is 90210 and at least 15 other cities (San Jose, Oakland, Santa Clara, Laguna, LB) based on what I'm seeing on my other boards.

He gave me a fix it ticket for loud exhaust. Hopefully I could simply change the invidia midpipe to the stock midpipe that I have stored in the garage and still keep the f sport axleback on since I dont have the stock axleback anymore. I have never heard a 350 with just the f sport axleback but I would imagine its not that crazy loud and I should be okay. But can anyone confirm that the f sport exhaust can pass a decibel check.

I got hit today with an exhaust ticket LMAO I downshifted/revmatched coming to a redlight and there was a cop waiting perpendicular to me chilling with his headlights off and I didn’t see him until I just hit the downshift but it was too late. Got it on my dashcam and damn that downshift sounded pretty good! LMFAO

Once you replace your stock piping (including CATS and resonators if they were deleted) your fix it ticket will go away

Now for my next tip, choose to take or it leave it... keep the stock midpipe on even after you get the ticket signed off.
If they catch you again with a loud exhaust (it takes about 5 seconds to pull it up)...and trust me, they will, your next stop will not just be fix-it ticket. You're lucky the cop was cool and/or that you were probably respectful to him, but really, it's no skin off their back to do a ref ticket, so consider yourself lucky.
If you have friends/family with modified loud exhausts... tell them to swap it back too as we'll probably also see an escalation to ref tix (and definitely just more fix-it tix) starting this year.

It depends who's looking and for what. Several of the tunes out there will set the emission ready flag just as it would upon reaching
I could be mistaken here, but I'm pretty sure all O2 sensors have data into the ECM just as before,, it's more so setting a flag that the data always passes so I suspect they opened the limits -/+ but I don't know. If it is based on changing downstream o2 limits, this would not be detectable without bit count and checksum verification of the ECM data.

I'd say right now we're at 10 out of 10 people with non-CARB tunes that get reffed, then get the tune discovered (based on my other boards). They probably know more than most board members on what you can do to a car.
It turns out, CARB is pretty powerful, probably more so than even the FED/EPA (at least here in CA, not talking about other states). So messing with your tune, if they're having a bad day or they don't like you for whatever reason, could be thousands in fines... for EACH offense. So Tune, non-CARB approved Exhaust, Cat Removal, etc can be thousands for each violation. So in a way, it pays for them to stay in the loop.

Sorry that happened, but it's exactly what I've been saying for the past couple of weeks on here. I'm seeing it everywhere in CA and mostly from my other car boards. That said, your stock Fsport muffler is fine, like I said above, it should pass. Put your stock midpipe back on and get the ticket signed off.
