Optional Lifetime Center Muffler
We're happy to announce our GT3RS Lifetime Center Muffler. It's available in 2 "flavors" Quiet and Loud. The Quiet 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 Loud is the muffler for those looking for no drone* at cruise, but a pronounced bark when getting on it!
We've tested the Quiet 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 GT3RS 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.
Lifetime Guaranteed including track use.
321 Stainless Steel coupled with a high strength design.
