We'll my car is at the shop getting the Magnaflow 3" x system installed. I know a lot of people think it's loud but on my Camaro I've run open headers and now just have SLP loudmouths bolted to the headers. Being only 26 I still like loud cars . So we will see when I get back. I'll post up a video. Another reason I got it is it's stainless. oh forgot to say it's currently a 340, the reason I went 3" is because I have a 440 laying in the garage which is going to be a 500hp/600ft lbs + build.
