If you are looking for a "street quiet" muffler at a reasonable $ ( as compared to the big name brand stuff), you might want to look in to the "Jones" line of mufflers. These are high quality all welded, all stainless, semi straight through design ( angled perforated pipe ) mufflers. Low back pressure in a relatively small package. I replaced some straight through Borla's with these. Much quieter at idle and cruise, but still some bark at WOT.
