Hi all

I'm having a drama with my 99 focus 1.8

In the last couple of days, I've notived a loud "whooshing" type noise whenever I give it any throttle. My immediate thought was a blowing exhaust and sure enough, there was no pressure when you put your hand over end of tailpipe (standard). I found a hole in the mid section pipe, at the top of the bend above the rear axle so booked it in to the garage to have it replaced.
Fast forward to this morning and they phone to say that it hasnt solved the problem. Any ideas what this might be? Before this happened I had agreed to sell to my brother and he has sold his car, he is due to receive mine tonight! Hopefully the garage will be able to source the problem but I just wondered if anyone else has experienced this before? The noise is definately passenger side because if I open the drivers side window I can barely hear it, but its very clear on passenger side.

Thanks in advance for any advice
