I need to know what muffler i can run and still be quiet. I have a 3" m2 down pipe, 3" atr high flow cat, 3" pfs muffler. The pfs is way to loud! I put the old stock muffler back on. The feel of the power is very different, almost like the sequential power band is gone. The engine redlines very quickly ( with the pfs ). Back to what i call normal with the 2.25" factory muffler. Is the racing beat muffler quiet? If anyone wants the pfs (3" stainless ) let me know.
