Great product. The exhaust tone is dead flat, no "ringing" or resonance at all much like factory original. It fits like it
should without any modifications or adapters. Only negative is that mine had sharp burrs at the edge of the inlet and outlet tubes. Not a big issue but worth being wary of. Walker Quietflow series will be my first choice if I need a muffler in the future. Now, do I get a prize for this unbiased statement?
