Do your right hand side tailpipes sit higher than the left side? And my guess is that the pipework is very close to the small metal bracket on the left of the rear diff housing?
If so the system sinply hasn't been fitted properly. All of the sleeves need to be fully pushed home and the mounting in the near to the centre section is adjustable. Once the system is installed and aligned properly there is no noise, clearence to the diff is perfect and it sits level on the rear. I know this as I had the same problem on my car after a rushed installation so I took my time the second time and its now perfect.
I had exactly the same issues due to installation. Now everythings fine.
"... on the smiles-per-mile charts, the 1-series M coupe can't be beat. It is a challenging piece, a triple-X-rated driver's machine for semi-professionals. Its handling balance provides an open invitation to indulge in latent oversteer, and provides an opportunity to separate the men from the boys. It is an absolute hoot on the track and an addictive plaything on your favorite twisty back road. "
