Make a selection FVD111LAMVER Having problems with your check engine light? Want to run cat bypass pipes or a free flowing sports catalyst set up on your vehicle without having to reprogram the dme (ecu)? This adapter offsets the oxygen sensor about 1.5 inch from the gas stream. This achieves, in most cases, a sufficient measurement for the air/co ratio and increases the tolerance range between the pre and post cat oxygen sensors. In addition, the sensitivity of the oxygen sensor is also reduced allowing you to run a nearly any exhaust or catalytic set up, including bypass pipes, without the need to reprogram your ecu! Use only for the 2nd oxygen sensor (after catalytic)!

Make a selection BBI9912020003 The bbi autosport 997 & 991 GT3 / rs exhaust side bypass is a direct replacement for the factory primary side mufflers. The primary mufflers are weigh approximately 44 pounds total while the bbi pipes are 4 pounds in comparison. For durability and protection against corrosion, each system is meticulously tig welded using 304 aerospace grade stainless tubing with lower carbon content. The result is a substantial reduction in weight behind the rear axle which significantly improves handling and less restriction to produce a much more aggressive exhaust note.

Make a selection BBI9912020001 The bbi autosport Porsche 991 GT3 exhaust center section is a direct replacement for the secondary center muffler. For those who desire a slightly milder exhaust tune, this piece is a great alternative to our cup-style side muffler bypass pipes. By retaining stock side mufflers and valves, the factory "sports button" feature is kept to conveniently switch back and forth between the aggressive "sport" mode during spirited driving sessions and the quieter, more civil "non-sport" mode for minimal noise on the highway.
