F**d exhaust sound but not exhaust :S

[Jay_clio]

noise began about 3-4 weeks ago and though that the exhaust had a hole , so went round to my m8t today to get in up on the ramps but had to lift the car up as it wouldnt go up them:dapprove: .

lifted and he went under, couldnt find a hole anywhere, so he asked me to fire it up and he managed to track down were the noise was coming from.
dont kno what its called but its this:
