Exhaust Question

It sounds like there is a bit of an exhaust leak somehere up front, I would check all four ends of your X-pipe, and check whether your O2 sensors are fully seated.
I have a few questions about the BBK long tubes for the 3.7L. I was wondering if anyone happened to know the difference in underhood temps between the stock manifolds, the chrome long tubes(should be vey close to stock temperature), and the ceramic coated long tubes(should be lower, but by how much)? Also, how does the ceramic coating hold up over time, and is it ok to use header wrap to further insulate against heat transfer to the general engine compartment, and the same for the chrome coated tubes? Thank you for your time.

We know for sure ceramic coating does drop temperatures, but the likelyhood of anyone finding the exact number in which the temperature decreases is going to be hard to find. Regardless, I do enough road racing to get the ceramic coat, so I would go for it anyway, it's not too much more, so might as well.

Im not sure about the actual temps but the chrome ones put off more heat than the stock manifolds just based on opening the hood after driving for a while. Luckily I have vents in the top of my hood so the heat from the headers goes straight up and out

The smell is coming from under the car near the rear, so my dumb butt didn't raise the pipe enough before I tightened the clamps...duh on me!
The only other smell is the ceramic headers curing.
