    Is the holes striped out? Can you go to a slightly larger bolt and tap the holes for those bolts?

    You get a bolt the next size larger. A tap will make the hole larger and cut new treads.

    these problems are usually caused by not having a proper muffler hanger attached to hold up the weight of the exhaust - a larger bolt may work, but I like to heli-coil them

    lager wont work, its a type of beer!


    theres been three terms here mentioned that you are previously unfamiliar with.

    a quick google on said terms would explain everything.

    TAP.
    LARGER BOLT (than the standard M6)

    HELICOIL.

    helicoils the best for the job, as you keep the M6 studs. going to a larger size causes issues with the nuts interfering with the exhaust pipe itself...
