Fabspeed Cat Bypass X-Pipe - Advice/Experience please

Recommended Posts

Hi there

Contemplating adding a Fabspeed cat bypass x-pipe to my 2006 997.1 C2S with X51 and PSE.

Will the bypass give more power?

CEL I can deal with via DME or 02 extenders, so this is not a worry.

Anyone here or heard a 997.1 S with PSE and Cat Bypass fitted, does it still sound nice and PSE ON/OFF still work?

Only more power very top end. And you will lose drivability and low end torque. It sounds horrible unless you like your beautiful Porsche to sound like a rice burner. Dont do it. My opinion. I did it and hated it..

Locutos, I have the same car, minus X51 and fitted the X-pipe last week. In answering your questions, no problem with CEL with O2 spacers fitted & PSE works fine. phillipj may be right about losing some low end as the car does feel that way. However, you feel a sudden surge once past about 4,000rpm and the car screams like a GT3. Expect a totally different sound from your standard set up. You won't wake the neighbors' though at low speed with the PSE at its default setting. The wife wouldn't know the difference until you floor it, and then she chews your ears off.......... Hope this is useful.
