Is anyone here running the Fabspeed Supercup exhaust? If so, I'd be very interested in your impressions of the system's quality and sound. Thanks.

No one??

7500rpm

PSE here, with Fabspeed de-cat X-pipe. Sounds a million dollars, but lost low end and drivability.

Hello rpm
can you be a little more specific on this?

thanks

I'm running Fabspeeds supercup exhaust with the 200 cel sport cats and x51 headers on my 06 C4S.

The system is very loud and aggressive, but that's the point.

I did feel a bit of power loss below 4k, but above 4k is definitely a gain.

The quality is great and the customers service was the same.

I can help out here.

When you do a cat delete on 996 & 997 cars, the low rpm cylinder filling suffers. The exhaust becomes so free flow that fresh intake charge is lost before the exhaust valve closes completely. We've recently made some updates to improve this for the street guys who want to run catless. It does sound really good, I can see why street guys opt for it.

is catless allowed on the street? and how would anyone know aside from the sound...

I do not see a location listed for you, but I wish I had a chance to hear this system firsthand. Where are you located?

Thanks Chris
just ordered the Supercups

in most states, you simply have to pass emissions once a year - some states less. it's easy enough to swap cats in and out, so some choose to run wide open. i prefer to run 200 cell cats and actually pass emissions with them in place.

Well, there's another set of Supercups I won't be able to hear firsthand - Dubai is a bit far.

I'm in Reno, Nevada.

I ran the Fabspeed mufflers on my 06 and 07 997 S. I did lots of DE's with these and they held up very week with no signs of any deterioration. Very very good mufflers, well built and sounded great.
