On Friday, I was pulling out of the parking lot of a local auto parts store. Their exit has a bit of a rise and a drop off that I forgot about. I heard a scrape and clunk when I was pulling out of the parking lot. Even when my car was the stock height, I use to sometimes scrape the bottom of the car on the concrete when pulling out.
On the way home, I noticed a new rattle that started to turn into a bang and clunk. Its not a really loud bang, but its noticeable. After letting the car cool down, I got underneath the car and found the passenger side of my H pipe was pushed up higher than the driver's side. So I loosened the bolts for the H pipe and repositioned everything. I have at least 1" of clearance between the H pipe, cats, and O2 sensors and the bottom of the car. Yet I still hear a banging noise when I go over bumps. I tried getting under the car and grabbing the H pipe and shaking it hard, putting my weight into it and also pushing it up against the car. Nothing seems to be hitting the car. I also checked the pupes near the rear axle and mufflers and can't see or hear them hit anything when I shake the pipes.
Today, I tried loosening all the bolts and repositioning everything again and I still have the same noise. I still have at least 1" of clearance between the exhaust pipes, cats, and O2 sensors and any other part of the car. Yet, I still have the same banging noise. I can't see any marks or dents to indicate what's making contact and causing the noise.
I also checked the bolts for the sway bars and shocks both front and rear just in case it was a part of the suspension causing the noise and everything is still tight and nothing moves around that shouldn't. Nothing changed about the handling of the car.
Any idea if 1" of clearance around all parts of the exhaust is enough and if there could be anything else that could be causing the noise?
