Not a lot has happen for 6 months now since my wife and I having our daughter. Family first! I did get a second job so a little money is finally going to the S4. Got my A/C working again since the compressor switch failed. Had to take off the front end to get to it. Thanks again for the help from my buddy Erik at I.P.M. Auto Service.
Went to Dan Fast Muffler & Brake and got a 3 inch custom cat-back Magnaflow exhaust installed. I did get a resonator install just so it wasn't too loud. So far it is sounding great! I know over time the sound will change so we will wait and see what it sounds like several months later. I do have to say the S4 for sure feel much more torque'e... if that is a word. Most people say they feel more power at the top end with a exhaust but I feeling it more a the bottom end. Maybe it is helping the turbos spool up faster. It was around $550 for parts and labor so I'm happy with the end result!
