Found my problem... The red circle is what's wrong. If you look in the small black circle you'll see a dark spot and this is where the suspension arm is contacting the exhaust pipe just in front of the muffler when it's under load and when I hit any kind of bump or dip in the road. I just can't see this being a factory job; I'm thinking it was some jakeleg @ jiffylube learning how to do exhausts... anyone else's exhaust happen to be like this or is it missing an arch to clear the suspension? This is a '97 Civic EX coupe with no suspension mods. Any comments?
