Vendors,
I need Borla Axle-Back Exhaust "S-Type" PN11924 and a 60610 X Pipe Kit.

Does anyone have in stock?

I have them on backorder already, but I do not wish to wait 4-6 weeks if there are on hand parts available.

Who did you order from?

They're on back order because they are redesigning the valves which can rattle. If you're buying one of these best to buy a new one when available.

I ordered from Maryland Speed, been waiting since the 25th :( but yea still waiting for my order. I actually had to put my old exhaust back on temporarily because I had no exhaust.

Then perhaps its worth the wait. The NPP/AFM valves are important to me, as well as 50% of my current problem with Magnaflow. The other 50% is a very unsatisfactory drone issue.

See video of my AFM valves slipping. I think the Magnaflow geometry is off. https://youtu.be/FW_rDFjLwj4

I've learned that these valves are likely all the same, along with the same faulty design. Perhaps the same vendor making all of them for this car -stock and aftermarket. I've heard enough videos to hear the rattle across all platforms and then had the problem with my stock exhaust. If Borla figures this out I'll pay for their exhaust and take back anything I've said previously. I still believe Chevy will end up recalling if enough fail because this is part of the emissions and while it's mostly a cosmetic annoyance if that's even proper, it's a faulty emissions component.

My early gen Borla NPP valves rattle. I need to open a warranty claim with them but I need to get my car back from the shop first and then make sure I can determine if it is just one or both rattling.
