NOTE: This is a very loud and aggressive exhaust system. We love it, but your wife/girlfriend/neighbors might not! If you're looking for maximum sound and performance, you've found it. 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.
Great, if you like it loud!

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 car’s 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!
997 Muffler Bypass

I ordered from Fabspeed after some lengthy research and the product was delivered as promised. The pipes fit perfectly and the job of installation was rather simple, with no extensive disassembly required. The sound is amazing and can be aggressively loud when really hitting the throttle, but that's exactly what I was looking for. I would recommend this product to anyone looking for this type of 997 exhaust modification.
