Hey Gang need a little help. I am looking to upgrade my 01 WR426 exhaust from uncorked factory to aftermarket. In most of the threads I read folks talk about the best performance with low DB output. I am looking for performance as sound is not an issue. (louder is better) Have any of you been tested with the uncorked stock pipe? How loud is it? I read all about different noise levels and I am not to sure where I am now. Thanks for your help.
