    You will need a small piece of 2" foam board, and an assortment of hole saws (not the spade bit kind).
    Now find out the tail pipe size and TB size. and get the matching holesaw bit.
    Note: the holesaw sizing is OD so you'll need to measure the ID of the bit.

    Do this for both tips and the throttle body. Get as close as you can. If the plug is to loose then snug it up with some duct tape or masking tape.
    I chose to make 1 for the TB because there's a chance both vlvs. on 1 cylinder might be open at the same time.

    Now find out what the OD is of your shop vac hose and put a hole in 1 of your tail pipe plugs.

    Now get your car on jack stands and insert all plugs including shop vac on BLOW.

    Now you can take your time and run your hand over the whole length of the exhaust. You'll be able to hear the air hissing out. Usually the leak can be fixed just by repositioning the clamp.

    Much more effective then the "New England Ghetto" way I have always done (wait for a really cold morning, start car and look for the puffs of white escaping where they shouldn't be)
