Hi all,
I've had my Milltek cat-back exhaust on for about three weeks now. When I was driving last week, I noticed a loud, harsh sound coming outof the exhaust upon acceleration in the 1-3K rpm range. I think this is only happening when the weather is cold(30 degrees F), but it sounds awful. It's extremely loud, and makes me sound like I have a coffee can muffler. After 3K, it goes away. Has anyone had this problem? Does anyone know how to fix it? I looked under the car, but couldn't find anything wrong. Also, I do have the aero kit, and my suspicion is that the rear bumper(which rubs against the exhaust is rattling due to exceswsive vibration. But the sound is way too loud for just vibration, so I dunno... :(
