Im new and have a question

[Venividivichi]

I just bought an 04 impreza wrx in red its fast compared to the 89 chevy celebrity i used to drive and beautiful in the snow cause well i live in buffalo and that is necessary on any car here.
But today i was goofing around of course in a parking lot and suddenly i noticed the car got louder much much louder like it had no muffler i instantaneously drove to the subaru dealership, and was like what is that? they said it was a seperation in the pipes i was like crap but then when i was pulling out the noise went away so idk if anyone has ever had their car repair itself but i havent and it has not come back so well anyone got any ideas on this issue i have an appointment to fix the noise that no longer is there but if i go back idk what they'll find

Welcome! If the dealership said that's what it was, then I would tend to believe them. The symptoms you describe match up with what they're telling you. If you're at all handy you could probably fix it yourself very easily.

thank you yeah i was thinking about looking myself to see but its so damn cold and snowy around here and i dont have a garage
but it just went away...?

I can understand not wanting to do it. I have a Cobb TBE sitting in my basement for almost a month now for the same reason.

I'm guessing a couple of the bolts holding two of the sections of the pipe have rusted out and the pipes separated, then either by braking or accelerating or hitting a bump they went back together. I'd guess it might be the connection from the downpipe to the midpipe since I think that's a donut fitting which would be able to hold itself together somewhat.
