So since I've bought the car two years ago it's had a magnaflow X on it and it's always had a slight lope to it, plugs, compression and leak down tests all come out okay. Now I doubt the car is cammed since I've always thought the idle was normal but now that I've heard about 4 terminators mine does sound different. I've heard bassani x's, prochambers, and a H pipe car and a stock mid pipe. The question is, why does my car sound like it does? It can't just be my mid pipe. It won't let me post the video here I'll get a YouTube link.
