991 GT3 with Race Headers vs 997.1 GT3RS with Race Headers
991 GT3 with DMS Race Headers vs 997.1 GT3RS with DMS Race Headers Great track day with a good friend. Jamie driving his 991 GT3 starting by chasing one of our customers, John, in his 2007 GT3RS Pumpkin. Both cars with Dundon Race Headers. John is such a good driver he keeps it close!
Both cars with Dundon Race headers! from 9/6/2016 The Speed Syndicate track day at the Ridge Motorsports Park. Fast forward to around the 2:00minute mark.
Quote from John (owner of the 2007 GT3RS):
"The acceleration of the 991GT3 with Dundon header upgrade is so ridiculous. The R8 V10 passed me this way before, but have never seen a 991GT3 like this before"
I'm very happy with it. In terms of affecting the cars outright performance, as such, I cant really say till I've been on the track, strip or Dyno with it - but Ill eat my hat if the car isn't measurably quicker in all situations. On a fast back road run for 150 miles it felts quicker for sure but in terms of lap... ~ Mark, Australia: 991 GT3 Race Headers
