I have always had a ticking sound even before I bolted on my new offroad h-pipe. Kind of like an injector click or even a ticking valve, but it comes from lower down and back like an exhaust leak, but I was never able to find one. Is this a normal sound. I have heard before that offroad pipes make a whooshing/ticking sound from where the H piece is and that is where it sounds like it's coming from. People say you can hear the valvetrain chatter more because of no muffling from the cats. If this is normal then I won't worry about it, but if no one else has experienced this then I guess I have a tricky leak somewhere. It only does it when it's under load, and you can only hear it really good with the windows up or when your driving by something like a guard rail or fence and you get that reflection back. I know stuff like that amplifies the noise, because when I get to open road you can't really even hear it unless your really trying to pick it out.
