My ER catless downpipe arrived today, so I found a local shop to install it for me. The shop people told me everything was great except for noticing an exhaust leak between the turbo and the downpipe, which is where the gasket is located. The shop also told me that since ER didn't include a new gasket, they have to use the old gasket from the OEM downpipe, which probably caused the leak. So I bought a new gasket from VRSF and drove my car back home.

The sound was great, got tiny burbles here and there as well, very enjoyable. However, I do notice a very loud rattling noise, I'm not sure where it comes from, but I bet it's somewhere on the new downpipe since the noise is not present with the OEM downpipe. It only occurs during acceleration, it's a high-pitched sound, and it almost sounds like some metal vibrating at a high frequency. I've attached a video below so you can get a better idea of the sound. I'm pretty sure it's not the turbo, cuz the turbo sounds very different compared to this one. This rattling sound sounds very scattered.

Any idea what it could be? The leak? The bad gasket? Or something else? Thank you!

I knew you'd find it when you installed the new dp gasket.
Congrats!
