Ever wondered what a 6th gen LS would sound like cammed with a "straight pipe" exhaust? :)

But it is not camed, correct? Video is captioned "Well, it's not really cammed, just the old vacuum line trick lol sounds SO sick though."

Haha I know right?! I practically sh*t myself when I first how it sounded.

Correct, it does NOT have a cam installed. It's just the vacuum lined pulled to simulate it.

Thanks everyone!! :D

New thread up!

Yep, just pull the vacuum line (or cap) off the upper intake manifold near the runners to make it sound like that.

I wouldn't suggest driving like that, it feels like it want's to die out at a stop so you'd have to feather the gas to keep it dying out. You also get a loss of power too.

IMO, I haven't had anything bad happen, just a thrown code from when I drove it like that before and it was a mixture too lean or rich or something, but went back to normal after you fix the vacuum leak and the code went away.

So, I wouldn't drive it like that because of that loss of power, the code and that mixture issue.

Certainly be fun to roll into my dads house sounding like that, (he had a 67 pony that sounded like that) but I don't think I'd drive it down 5 miles of gravel road with it like that :/
