Looking for a good quality sports exhaust - ideally Eisenmann or Diablo? I don't know a huge amount about them so perhaps there are some other good ones out there so any recommendations would be welcome.
Depends how noisy you want it. RPI is another option that's really loud. I have a Remus system (they also make the Schnitzer back boxes) which is a modest increase in volume with a wonderful base addition to the soundtrack and great harmonics at 3-4000 and 6-8000 rpm
