Downpipe and turbine wheel whistle
This might sound like a dumb question, but do aftermarket downpipes make the exhaust turbine sound noticeable inside the car. The reason why is my buddy put a turbo xs downpipe on his wrx, and you can hear the turbine wheel spool inside the car. It sounded really sound so I was just wondering.
Thanks

I did turbo back exhaust and ram air intake and there was no noticeable whistle, lots more woosh and psshh but no whistle. I swapped the stock turbo for an MHI 18K and now it whistles a lot, any time I'm accelerating beyond 3000rpm it is clearly audible if not loud.

That the anti-surge compressor cover, not the turbine.
