Oddball question of the day:

My exhaust pulsates strongly at idle. Is this normal?

If I hold my hand near the exhaust pipe I hear a rapid foof-foof-foof-foof and can feel the pulses of pressure hit my hand. It's pretty strong, much stronger than any other car I have owned.

Is this a function of my exhaust flow characteristics or an indication that something is wrong (leaking valve, nonstock cam?) or is it perfectly normal?

Just curious...

probaby emphasized due to short length of exhaust system and/or narrow pipe compared to front engine cars.

Mine does that.. in fact I was just noticing that yesterday while I was trying to determine if it was running fully on all 4. I never notice with my last 914 because it had 4 exhaust tips.
