I had a borla on my previous 05 legacy and absolutely loved the sound. The cobb i have now is a little too loud but id love to be able to keep the y pipe. My intention is to purchase two borla mufflers and get an exhaust shop to fit them in. I do not know which muffler is used in the legacy cat back and i cant find any that even look like it dimensionally speaking. I emailed borla to no avail. Any input would be greatly appreciated. Thanks!
