911Tuning Exhaust System Porsche 996TT 01-05 - w/ Catalytic Coverters 911TUN-996TT-100-w-cats

911Tuning is a new comer to the Porsche performance parts world but they come in with a spectacular product with great fit and finish. The 911Tuning X design muffler for the 996 Turbo features a full 3 quot piping and a choice of loudness based on a cat or catless design. The catless design does produce more power as well as much more sound.  The design utilizing the 100 cell stainless steel metal matrix cats on V bands will be quieter and more restrictive, which will reduce the overall power potential. This muffler system is hand made with an attention to detail to ensure a quality product suited for your Porsche 996TT.
