For the guys with burble tune
Been enjoying this medium burble tune i received from DME. I'm currently am running the performance exhaust, stock downpipes with a secondary cat delete and it's been awesome. This morning when I started up my car, there has been this weird xylophone sounding thump inside the muffler. Is this normal? I have attached a clip.
Edit: Forgot to mention it does not make this noise when the valves are closed.
