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... read more

Most of us have experienced the many issues associated with both the stock Steel and Ti rear mufflers on our beloved 997.1, 997.2 , 991.1 and 991.2 GT3, GT3RS and 911R. cracking, holes, not passing sound etc...  We've been reinforcing both the Steel and Ti versions for years after they crack and understand why they fail quite well.  We set out to fix the weakness of the OEM center muffler and include an option for those that want their car to pass the more and more prevalent dB restricted tracks without losing power.  We finalized the design and have tested at numerous tracks both for longevity and for dB reduction.

We're happy to announce our GT3 Lifetime Center Muffler.  It's avaialble in 2 "flavors" Orange (Quiet) and Black (Loud).  The Orange is for those customers looking for no drone* while cruising and to quiet the car at full boogie to attenuate some of the dB levels on the track or on the street.  The Black is the muffler for those looking for no drone* at cruise, but a pronounced bark when getting on it!

We've tested the Orange on a 991 GT3 with side muffler deletes that was 104dB before the muffler and passing a 90dB day after .  We've tested on a stock 991 GT3 and the car passed where it hadn't previously. And we tested on a 997.2 GT3 that had not passed at Laguna and passed a 90dB day.  We've recorded the Orange GT3 Center Muffler in our own testing at 10-12dB reduction over the OEM GT3 Muffler.  All of the testing was done on cars WITHOUT GPS Exhaust flap closing devices.

* for no drone performance, the cars must maintain valves and use both the upper and lower exhaust paths in the muffler.
