At about 3,000 RPM, the exhaust seems like it's rattling somewhere. My friend told me that it was my radiator leak making the noise, but now I have a radiator and it's still doing the same thing.

I checked the exhaust and nothing seems wrong.

Thanks in advance :]

our exhausts are made of 409 stainless steel, they dont require any mantinence, other than replacing the cats and or flex pipe when they fail.
chances are any exhaust you have made wouldnt last 1/2 as long as the OEM equipment.

replacing a flex pipe isnt patch work, the flex is designed to do just that, "flex" and take the load off of the piping.
over the years, the flexing causes the strands to crack and break, its part of the deal.(along with the fact that the flex section isnt stainless.
