I currently have the roush axleback on my car which was my first and favorite mod. I want to add an off road xpipe to squeeze a bit more power out of my car. From the reviews about this setup sounding obnoxiously loud I decided against it. I like the quad tip exhaust that magnaflow has that looks like the GT 500 but heard it on a buddies boss w/ xpipe was and was too much. My question is I love the sound of my roush and dont want to change that even if I dont get an xpipe. Is there a way a custom shop can simulate the GT500 tips to fit on my roush of couse if I purchase the rear valence from 3D carbon?
