Why do American cars sound 'heavier' then European cars?

Because Americans love muscle cars. Didn’t you see the movie American Graffitti? :-)

It’s due to the engine and exhaust system in the vehicles.

Coz the yanks have Barry White chewing on wasps under their hoods.At least sounds that way.Also exceptionally inferior cars on the whole, just sayin.

@ucme – ”...Barry White chewing on wasps….” ROTFLMMFAO!!!!

Big V8’s may be the reason. I have an 80’s Ford with a German V6 up front and all the kids love the noise it makes.

It is actually party of the original peace treaty, signed at Trent, after the Revolutionary War. It’s a subtle and constant reminder that we are the champions, my friend.

There made with good old Detroit Iron….

Unequal length of downpipes can create that lumpy american sound. Aggressive cams will do this as well. The deepness has to do with the length of the exhaust and large diameter.

I don’t think they necessarily do. The Europeans can do big V8s too. American manufacturers are just unimaginative and use V8s for every sports car they make, while the Europeans experiment with V10s, V12s, boxer 8s, turbochargers or natural aspiration.

Because some Americans think CO2 is fertilizer.
