Lighten the rear of the vehicle while adding aggressive sound by replacing the heavy factory mufflers with straight-through tubes. The pipes completely replace the factory mufflers and retain the stock Porsche tips.
SOUND:
If you're looking for maximum sound and performance, you've found it! This is a very loud and aggressive exhaust system. Expect ripping sports car sound from your flat 6, at the cost of some interior drone. If you are looking for a more subtle and daily-drivable upgrade, we recommend checking out the Maxflo Performance Exhaust or the Supercup Exhaust System.
POWER:
Excellent power gains can be seen across the power band. Awesome mid-range torque you'll feel out on the street, and top end HP that you'll feel on the track. As you can see in the photos, our dyno results show 21 whp and 21 ft/lbs of tq.
FEATURES:
Excellent quality. Installation went perfectly. Product performs as expected. This was my first Fabspeed purchase. Very happy, more to come.
If you like it loud then the muffler bypass pipes are for you! Received pipes quickly for my '07 911 C4S. Sounds decent at high accelertion and would probably have been even better on manual trans. Did turn a lot of heads! Sounded "cheap" at low speeds, but could be because of my automatic trans. There was lot of droning and made my dashboard rattle. Videos of the muffler I watched didn't sound as loud as it is in person. Even my 18 yo son said it was really loud! I spoke with a rep afterward and he said on a scale of 1-10, with 10 being the loudest, these rated a 9-10. He said the Maxflo full exhaust system for my car would rate a 4, which would be better for me. This particular product was just too much for me. Good product, nice people, and would order thru this company again, but I would call first to get the specifics.
Fairwind installed my new bypass pipes yesterday afternoon and I am VERY happy with them. My cars engine now sounds like it has cojones! During highway cruising, 75-80 MPH/ 3K RPM, the sound is very sedate/acceptable but when I get in the gas, at any speed, the motor comes to life with a guttural/rasping roar very similar to Maseratis & Ferraris I've listened to. I have noticed no droning and the engine seems to be very comfortable with no check-engine/engine computer issues. You folks have been great to deal with & I plan to let all my friends in the PCA know how pleased I am with your products and, of equal importance, your customer friendly attitudes; very refreshing to say the least!
