I mean without all the mufflers and stuff strangling it to death? Yeah. Well, I have. Or I did. Until I got around to pulling the back half of the exhaust system (from just downstream of the cat back) off my 560.

So it's still not completely open as the pre-cat and the cat are still there, and the recording I made isn't all that great because none of my mics have the frequency response range to pick up anything much below 100Hz very well... which is, of course, where most of the noise the car makes is.

However, for those of you that're curious...

^ That's what a 560SEL sounds like with no muffler or resonators.

lol **** sounds liek a muscle car, german muscle! haha i got an 89 benz w/ no resonators, stock muffler tho.

Soounds pretty good.

It get old real fast having to listen to it on the way to school/work though.

My 1991 560SEC has very high flow cats, 2 cherry bombs for resonators and a 70 Series Big Block II flowmaster muffler. Sounds like a V-8 is supposed to sound!

Sounded like some thunder storms here to me

You know, it's funny that you mention that. I've had them off for the better part of a week now... I've considered putting them back on once or twice, but then I go out and start it and I change my mind. It's actually not that loud... my dad's '71 Firebird, which has a flowmaster 40 series on it, is louder. Went by a cop who was writing a ticket at about 3500rpms today (I was across the street) and he didn't even look up.
