Soooo after in instaled the o/r xpipe (no cats) and no mufflers was on for a week, at first it would be loud as hell if I gave it any gas at all no matter the rpm range. Now after being on for a week (no tune for it check engin light still on). I have lost like all of my sound and it's loudness is only if I floor the Peddle and some times it only lasts for 2 seconds then goes away. The live data reader says their is a fault in my exhaust. Could that be the reason for my sound loss? My car also likes to have stupid spurts of ludness for like half a second at random times, i miss the sound i use to have, everybody tells me im just getting use to it, but i dont think so if all my friends have told me it has changed and dosent sound like it use to. Any help with what this problem could be would be great!
