i just got my Yonaka catback exhaust for my ‘11 civic coupe (LX). I had it installed by my mechanic, and it’s rattling.
At first it rattled in when the car was in Reverse, my mechanic said it’s a little too long/big for my car so he cut a little piece of the frame. It didn’t rattle...
So I’ve just noticed yesterday that when I go over 50 miles per hour, there is a sound from the front of the car that resembles little rocks being dropped onto a thin sheet of metal.
Anyone have any idea what this could be? I don’t think it’s anything mechanical but, you never know...
I recently developed a rattle. Seems like its coming from the head area. Does not rattle on cold startup but when operating temp is reached it starts making a bad rattle noise. Noise goes away after 1500 rpm. Sounds like someone threw a bunch or rocks in the head. What could it be?
