Any actual experiences with Fabspeed Cat Bypass Pipe on 2003 'S'
 

Does anyone have any actual experiences with the Fabspeed Cat Bypass Pipe for 2003 'S'
I was thinking of keeping the stock headers and stock muffler.
What kind of sound can I expect and how difficult is the entire installation for a less than average mechanic?
Thanks.

Despite my fitment issues with the Fabspeed (mainly because of my custom engine install), I am quite happy with the sound and power of the Fabspeed system - I'm running catless headers, catless mid-pipes, and their sport muffler. The system is not nearly as loud as I thought it would be - it's got a nice grumble, no resonance, and, if you put the top up, it's doesn't drown out the radio.

If you're running a stock setup, my guess is that you wouldn't have much of an issue with installation. However, if you're keeping your stock headers and stock muffler, I doubt that the sound will be much different, nor will you notice much in the way of power gain. I would recommend that if you are going to do it, go all the way with the full system.

I have Fabspeed pipes on my '02 S, which is nearly identical to your auto. Fitment was easy; just a bit of wiggling with pipes to remove the secondary (heavy) cats. I also have a modified sport muffler by Oettles...sound is great...like a little GT3RS with no resonance or drone.

To JMatta,
Are you able to pass emissions inspection without the secondary cat?

Not an issue in Illinois...they are not part of the O2 sensor system and appear totally redundant, since the primaries are incorporated into the exhaust headers. Never had a CEL in all the years since I installed them.
