Make a selection BES99120040S Take your 991.1 or 991.2 turbo or turbo s to a new level with these muffler bypass pipes. They produce the wildest sound available on the market today and are a perfect upgrade for level 3 or 4 car used on the track. They produce loud, low, deep tones with exaggerated turbo whistling and sinister gurgling and crackling off throttle. By far the best sound you can get out of your turbo, not to mention being able to shoot flames! The only real drawback is the drone in the cabin which we try to minimalize by stepping down the diameter in 3 stages. Features: - + 35 crank hp & + 25 crank torque - 3 tubing (75mm) that tapers down to 2.25" (57mm) to prevent turbo damage. - weighs 7 lbs.

Make a selection BES99125010SK Are you one of those that are looking for more sound from your Porsche sport exhaust (pse)? Perhaps it's not quite as aggressive as you would like, or your last Porsche just sounded so much better? Don't worry, we have you covered, and the beauty is, you don't have to touch the catalytic converters which is a big no, no with Porsche dealers. With the valves open you receive a far more exotic, rich, deep, turbo motorsport tone and with the valves closed, soft subtle, completely stock sounds. So, absolutely no compromise and you will be thinking, the car really should have left the factory like this! Features: - + 10 crank hp & + 8 crank torque. - weighs 29 lbs.
