I bought a civic vti and when running the car the vtec didnt sound as loud as the test drive.
the seller told me that was because he removed the 'whales penis' modification which I had agreed to. He then disconnected the pipe which goes to the air filter and said you can leave it like this it will sound louder.
I asked him wouldnt that cause damage since the filters not connected he replied 'not really'.
I'm not sure if the context of his answer was temporarily or long term. In any case could leaving the car with the connecting pipe removed cause air damage in a temporary or long term scenario?
