Does a cam change the volume of an exhaust note?
Does a cam change the volume of an exhaust note? I know that some cams, esp those with a lot of overlap, tend to add a lope to the idle, but will a car actually get louder (or quieter, I suppose) with a cam.
And I don't mean valvetrain noise, I mean exhaust note.
And for that matter, how about heads?
And for that matter, how about a stroker kit?
Thanks, folks.

Just did H/C and when my wife first heard the car her comment was "that can't be street legal anymore" so for whatever reason yes it does get A LOT louder after H/C. I want to get back to the pre H/C noise level.

More powerful explosion=louder exhaust and more hp and tq
Wow. Thank you everybody. That is quite encouraging. Yet another reason to go for H/C!
Great sound, JRP. It sounds meaner, but it's hard to tell how much louder. I'll take your word for it, though. And I assume the difference only gets better as you apply more throttle.

Yes, after my X1 install, it went from being a stock car with a semi-loud exhaust to sounding like a race car. Definitely louder, there's a lot more violence going on in the cumbustion chamber with the bigger cam, more air, more fuel, more powerful explosion, hence, louder!
Freakin' cool too...

definitely louder. But is also louder at idle and part throttle so i beleive the loudness has less to do with the more horsepower theories described above and more to do with the additionally cam timing allowing more sound to escape.
