Next, check the hoses & gear clamps on the other ends of the y-pipe, left and right side of the engine bay. They route down underneath the car but you can see the y-pipe connections from under the engine lid. Ensure they're seated properly, gear clamps right, etc...

Lastly, by putting the rear of the car on jack stands, you can lay on your back and see the hoses that connect to the intercoolers. Check them for same issues.

I think that's about the limit of what you can easily check without a hoist or more technical capabilities. Hopefully it's one of the hoses in the engine bay and a quick fix. My throttle body hose came off many times, no matter how many times I replaced the gear clamp. Replaced the hose and issue is fixed, oil residue had expanded the original hose and it would no longer seat correctly.

Good luck
