Installer for racing beat 4-2-1 manifold plus remap

Hi. Can anyone recommend a reliable garage to supply and install a racing beat or similar MoT compliant 4-2-1 exhaust manifold (with remap) to my 2.0 sport tec?

In the area of Lichfield, Cannock, Burton, Derby, Telford or Tamworth.

Thanks!

Ilkeston, near Derby ?

Not used them personally but my NC had been prepped , checked over by them for local dealer I bought my car from few years back.
