I feel stupid...exhaust question
I was noticing today that my car's exhaust (03 325xi) only comes out of one of the tips on its dual-tip. when i plugged that tip, i could feel it on the bottom of the muffler, behind the tip. It doesn't sound like it has a leak or that anything is wrong, but now its got me wondering. so, am i as stupid as i feel? go easy, and if you can squeeze in something useful, that would be great.
