Ok so for about the last 200-250 miles, I have had a rattle that I can't pin point. Now that I have exhausted all my personal knowledge and the internet is letting me down, I am bringing my issue to the find folks here...
The sound only happens around 1800 RPM. Only really seem to notice it when I am down shifting and when it hits 1800 RPM there is a pretty good metal on metal tapping/vibration/rattle going on. Does not seem to happen when I am in neutral...but I have heard it once or twice.
Thought it might be the muffler since the last time I heard something similar it was a weld in the muffler that cracked. Checked the muffler thoroughly and I don't see any cracks this time. This is the Side exhaust that comes with the Hahn Turbo kit.
I have checked for any loose screws, bolts, and all the normal stuff...especially around all the mods.
It drives and runs like it has for the last 7K miles with the Turbo kit on it. All Fluids look like they are in good shape.
I am just at a loss. I am going to post a video with the sound later to see if it helps. Just wanted to put this up so I don't forget to do it.
