Today is the day I get my S4 back. Michael at Apex Performance and Fabrication (also found on Facebook here) just sent me these pictures last night.... and all I can say is WOW, just amazing work. If you live in the PNW and need exhaust or other fabrication (they do lots of stuff) I certainly recommend this place.

My initial thoughts of the sound? Yes it has some rasp, but the more I drive the more that seems to go away. So far I think I've put many 100-200 miles on it (video is showing zero miles) since I got the car back and every heat cycle the tone has gotten lower and less raspy. I will say this is much louder then before, I'm a little undecided if I like it or if I need to add some resonators back to it. Likely in a month or so we will have true idea of the sound and a update video to follow. Subscribe to my YouTube channel here.

If you've seen my car in person there likely one thing you've noticed is my low hanging exhaust piping. Not a subject that I've wanted to talk about as I could have likely gotten it fixed a few years back, but I really did not like the place that I went to. When my wife noticed it a few weeks back I knew it was time to get it fixed.

So I went to a local muffler shop (mufflerkingperformance.com) just down the road and had them fix it. Told them while they were at it to go a head and remove the resonator as my exhaust just seemed too quiet for my likely. I don't want to wake up the neighbors... but I still DO want people to hear me as I'm passing them at full WOT!

Anyway, two hours later and for $120 my exhaust was finally the way it was suppose to be. They replace the piping from the cats to the muffler. Now I just need to clean it up and give it a wash, polish the tips, and likely take some steel wool to get ride of a little rust around the old welds. I'll give it a few months and will do a new videos so you can compare the sound difference.

I'm sorry this took so long to get up. I know a lot of you have been asking for this video and I wanted to make sure it wasn't crap. I also wanted to make sure the exhaust was fully broken in. I do have to say that Audi did a great job keeping engine and exhaust noise out of the cabin because it wasn't until I make this video did I really notice what this exhaust system sounded like. I how you guys in enjoy the video!

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!
