3000GT-GTO

Guys my 2012 GSR is making very loud pop corn noises from the Exhaust after engine is shut off. Not sure if this is normal for this car

I have taken this video from my phone let me know what you guys think, is it heatshield loose or something like Cat broken?

Noise goes away after 5 minutes of car cooling down

I think that is normal. Metal cooling and contracting but don't quote me on that.

mine used to do that sometimes too... not that much or that loud though. i think it has something to do with the cat because it went away as soon as i installed a high flow

I only got 2500 miles on the car now I figured its exhaust breaking in, but it gets pretty loud that when i am in tunnel or overpass I can actually hear it with the engine on.

when it gets older it will be less noises.

Mine now has 800 miles on it and has never made that noise. I doubt that helps you but I'm not sure it is normal. Atleast not that much and that load

It only does it when the car is fully warmed up, its very noticeable if you park your car in garage a lot less noticeable on streets.

I dont park mine in the garage so maybe I'm just not hearing it. I'll start checking after I park the car and let you know. I've circled behind the car a number of times and havent heard that sound. Atleast not that load. But I'll start getting up under it and listening.

yes. normal. mine does that. so did my previous suby legacy gt and wrx.
metal cooling and expanding. many cars do this actually, most of us just probably don't notice.

My RA was making the same noise, I have 15000km on mine, it was really annoying, so I took the heat shield off and now no noise. I noticed all aftermarket exhaust have no shield, so I assume it is fine to run it without the shield. What do you guys think, any damage that could be caused by this?
