Here is the deal. When I get on the throttle I hear this distinct sound, it sounds like it is coming from the driver side. It sounds like an air hose has been cut. Fairly loud WHOOOSH. It almost drowns out the exhaust. Not at lower RPM, only when you get on it. I had the muffler shop do some checking as it almost started after the new pipe went on. It could have been after the injectors got changed as well. Could an exhaust leak sound like this? Any idea of what to ckeck first. Any help here?? :confused:

almost sounds like a cac hose or clamp not tight...
