Porsche 996 - Exhuast noise increase
We have two options for the 996 - One is a replacement sport muffler that takes the place of your OEM muffler and the other is a replacement sport muffler with sound valves, which allow it to go from sport to loud mode at the touch of a button.

Do these weigh the same as stock or is there a savings to be had? Also, can either of these be used with cat bypass pipes? Lastly, do you publish install instructions for the unit with sound valves so I can assess the LOE and if I can DIY? thx
Obviously it is a little more aggressive than with the cat's

Yes, we have installation instructions - I would require your email to send them to you - if you PM me your email, I will send them...

your sport mufflers with valve looks kinda OEM PSE.
I have theh OEM PSE in my 996. My question is will your system work with the OEM Porsche Valvesystem because i have already installed the switch button inside my car. If needed i would only change the mufflers..
Hope you can help me out!!

Yes, our valves mufflers will work with the OEM switch, wiring and plumbing, except our solenoid is the reverse of the OEM, so you would have to replace the OEM soleoid with ours. All the existing wiring and plumbing would be retained and it would be a very easy installation.

I know you were asking about the Fisters, but I have Fabspeed on my '99 and LOVE the sound. To be fair I haven't heard the Fisters, which clearly have a loyal following. I like the option of being able to return the car to stock so preferred the catback system. It's also a fairly easy bolt on DIY. I'm sure you'll love it either way, just sharing my $.02.
Exposing more people to the awesome sound of the flat 6 is a good thing!

Fabspeed new is going to be much more than the Fister mod, but you save weight and can turn it back to stock. May not be a big deal, but that was my justification. I also found a used system on this forum for less than half of what a new system goes for.
I'm sure you'll be happy either way!
