Which Exhaust System On 821

  1. Hi all
    Looking for a system for my 821. The Austin Racing has really taken my eye. Excellent reviews and great value at £799 including headers.
    Any thoughts
    Cheers

  2. Hi Mike,
    I just took a look at the website out of curiosity. All I can say is that it's going to be loud as F**k.
    However, that's not a deal-breaker if you're ok with that.
    By eliminating the cat, you should also budget for a Rapidbike A/F re-balancing unit or a ECU flash to take advantage of your newly found free flow.
