    2016 commodore sv6 series 2
    Hi All,

    I am new to this forum, I have Holden Commodore SV6 2016. Last week I have replaced original exhaust with XForce CAT Back exhaust system from a local workshop they have very good repute in exaust systems. Now I am thinking that I did the mistake to get it. There is too much noise or drone in the cabin. I am new and don't have any idea what to do to reduce or finish the noise/drone in the cabin.

    I feel heavy head if drive my car for a long time.

    What could be the solution?
    Thanks in advance.

    Sam

    Talk to the exhaust place who supplied it and tell them. They need to swap the mufflers or add noise suppression to the system.

    They should have told you that it would be loud and droney before you got it. As above, different muffles to reduce the volume of the noise but in my experience droney and awful is what a V6 sounds like with an exhaust on it.

    Ask for a refund and put the stock exhaust back on :)

    I have a full X-Force system with Varex mufflers . I hear the stuffed rear bearing whine more than I can hear any drone . In a wagon .

    Exhaust probably too big or missing mufflers.

    Thought you were warned in another thread about this.

    Hi Guys,

    Thanks for the reply and sorry for the late reply from my side. I have replaced the mufflers with Varex and now no drone in the Car and sound is good as well. converter works very good as well.
