Hi Folks.

New to the group so hope i posted this in the correct place.

I have a Fazer 600 Year 2000. Just had the downpipes changed because the noise the engine was making sounded like the exhaust blowing. 1 of the studs had broke so when the engine warmed up i thought that was expanding and causing the blowing noise.

Changed oil and filters also.

Did a trip to work and back yesterday (Aprox. 15 mile round trip) and when i got it home it sounded like exhaust blowing again. The noise gets worse the longer the engine been running.

Any idea's of what to look at next would be greatfully recieved.

Thanks in advance
