For those looking for a quieter alternative for an exhaust system, I just wanted to pass along my experience. I have experimented with quite a few different mufflers over the years looking for the right mix of performance sound that isn't too loud for an old guy. I have had OEM, OEM without cat, dynomax turbos, ultraflows, OEM turbo style, and now finally Hooker Aero chambers. Current system is 3" DP with Random cat, ATR 2 1/2" dual stainless, and side-in side-out Aeros. I gotta say, for me the sound is perfect! Still get a little drone @2000 rpm, but nothing like the ultraflows without cat. The car is for the most part quiet but wouldn't be mistaken for stock. The closest thing I can equate it too is the stock system with the cat off, but I think I'm flowing way more this way. Everyone's preference will be different, but I'm finally a very cappy hamper
