So where on the exhaust to i check for leaks?

If you can't see any holes, check the joins are all tight

Start the engine, have someone partially block the exhaust using a rag over the end and then work your way along from the engine down the length of the exhaust while listening for the telltale hissing of exhaust gasses escaping where they shouldn't be.

If the pipe is cool you can put your hand over the exhaust pipe to seal it. You'll soon know if there is a leak that way.

Start the engine and have someone put something (the sole of their shoe?) over the tailpipe. This will have the effect of making any leak more obvious. Look by cupping your hand/s around the pipe, without actually touching it, and then run along the entire length of the pipe. If there is a leak you will feel air puffing against your hand. Be aware that there is often a hole underneath towards the front of the muffler. This is to allow any water, either rain, washing or condensation, that gets into the muffler to drain.

I'll have a look when we go for a ride. I'll bet you anything it's a high-flow exhaust that hasn't been jetted to suit. Everyone does that. Dummies! (not you, the person you bought the bike off).
