Seal the hose in the exhaust pipe to minimize leakage. You will have to block off the other side of the dual exhaust as well to help build pressure. Then you can use soap/water solution which will bubble up where leaking. If a large enough leak you should be able feel it with your hands. Ron

You may only have a minute or so to do it so be ready when you fire it up. If nothing up top put the car on jack stands and repeat. If it is headers with 1/4 flanges then you need gaskets at the heads and at the collectors and then retest. Careful, your character's showing!

Put one end to your ear and put the other end along the exhaust joints and connections. When you get near the leak, you will know it. If need be, you can twist a piece of solid wire around the hose so that it can be bent into 90*s and such to get at the spots underneath things. Master, again and still

Thats what I do. I just use the hose part as its just like using a piece of vacum hose up to your ear and you will know when you find it. Best way I found to track down an exh leak. Ron
