Just installed an exahust, Is this normal?
I'm only guessing, but there may be nothing wrong. Aftermarket exhausts are notorious for drone, especially in the 3-4k rpm range, and can be more than some people want to endure on a daily basis. The good news is that a HFC/test pipe will help alleviate the drone but the overall tone is going to be louder. As you mentioned, just double check everything when you put the HFC in and see what the results are afterward.
I think I am still going to retorque and check for leaks just in case.
