So, my friend has a 92 Si, I have a 94 Si and my question is what causes the engine to roar? I know it might make no sense but when you rev the engine it makes a noise, gets louder the more you rev it, but my friends H23 sounds way different than my H23. I was wondering why is this? exhaust? Worn out engine? Valves? I don't know if this might have an answer lol. I don't know how an engine with the same exact parts can sound so different.

A dumb question is- How much wood could a woodchuck chuck? If a woodchuck could chuck wood?

A: A woodchuck can chuck as much as a woochuck could chuck, if a woodchuck could chuck wood.

More then likely theres a difference in exhaust, or intake, both greatly effect sound.

Agreed. All of these will make a difference. Go and take both intake pipes off and rev them up open throttle body. Hopefully you don't suck some dirt in

lol exhaust leaks for sure, even having an aftermarket muffler will change the sound(even if its oem designed).

Having your valve lash or one of your cams off a tooth rahtard/advanced might cause different tones
