QUICKSILVER PORSCHE 911 GT3 AND RS (991 GEN 1 AND 2) - SPORT SIDE MUFFLER DELETES WITH SOUND ARCHITECT™ (2014 ON)

QUICKSILVER PORSCHE 911 GT2 AND GT2RS 997 - RACE CATALYSTS 300 CPSI (2008-11)

In our testing, we found that the best result came from replacing the OE side mufflers with a tube assembly that incorporates original-type valves - The benefits are:

Valves continue to operate via the cabin button

Significant weight saving - over 30 lbs

Plug & Play - These require no other modifications.

This emphasises and amplifies the great original sound, and all it's elements.

With this option and the valves open, the exhaust is basically straight-pipe.  Sounds fabulous....  Aggressive and sharp with all the crackles and you can turn it down when required.
