ero1220 Posted August 28, 2004 Report Share Posted August 28, 2004 All summer I have been reviewing different exhaust options for my STS. I decided to go with Dynomax Super Turbo mufflers and upgraded the Y-piping to 2.5" to handle everything... you should HEAR this thing. It feels like a brand new car and the rumble is great. I'm really satisfied with this mod. At idle it purrs like a kitten and it roars on throttle. Combine this with the K&N drop-in and the car really digs in on WOT... it's great, I love it. My only gripe is that the quad tips stick out a bit (~3 in.) but it's just something I have to get used to. I have a few pics here along with some pics of my old STS.
