    That sounds too clear to be internal. Are all of the accessories new used installed correctly?

    i believe so, i’m going to disconnect the accessory belt after i finish work to see if i can narrow it down, i’ve had a couple people tell me it could be the exhaust? could an exhaust leak even make that sound?

    Did you find the answer to this?
    It does sound like an exhaust leak but he clip is to short to tell.
