Fabspeed MSP just released the dual-canister Maxflo Mufflers for the Porsche 957 Cayenne V6 vehicle. We have received many inquiries regarding the V6 platform, and just this past month we had a local customer stop by with his Cayenne to install the set. These are the same Maxflo Mufflers used for the 957 Cayenne S/GTS/Turbo, and are in stock - ready to ship. Fabspeed installed this set of Maxflo Mufflers with Deluxe tips and Secondary catbypass pipe to improve the sound and power of the V6 engine.
The Secondary catbypass pipe is a direct replacement and will not set the CEL as you are replacing an unnecessary set of catalytic converters. The Maxflo Muffler system is also a direct replacement for the large factory system, but you will need to cut the stock muffler in order to remove. The Maxflo Mufflers will clamp onto the existing OEM exhaust piping and you can either use the OEM tips, or Fabspeed's dual-style polished T304 stainless steel tips. Please visit the Fabspeed website for more information on Porsche Cayenne performance products.
