The theory on an X pipe, if properly designed, is that the sequenced pulses from one side of the engine moving through the X help to draw the exhaust from the other side out and through and vice versa, actually increasing has Velocity out through the exhaust. In theory, I can only see the is working if the exhaust also has equal length long tube headers, otherwise the pulses wouldn't seem to be in sequence to me. I have both Fabspeed long tube headers and their X pipe on my supercharged 997.1.

Nope. No problem washing or high (eg 120+) speeds. Did have huge storm with 60+ mph winds, rain that literally was a flood 1-2’ high slamming side of z3 like a hurricane take one off. I was shocked no water in car. Luckily didn’t last but 5-10 min while creeping on fwy coming home from airport. Tornado sirens going off, radio filled with take cover alerts. Yeh right I’m stuck on fwy and no where to go.

For me, the x-pipe is only a consideration for sound. I’m pretty skeptical of any real performance gains for anything that is a simple bolt on piece of kit, and for me it never entered my Decision. This was the cheapest center muffler delete I found.
X pipe doesn’t work on every engine and exhaust configuration. The correct placement of the crossover is not only dependent on the layout of the exhaust, but the optimum location changes with rpm. That means placement of the crossover is a compromise on a street driven car because the car isn’t being run for long periods of time at a constant RPM. That being said, the best place for the crossover is almost always pretty close to the collectors on the headers. The idea that a crossover placed just anywhere along the exhaust path magically increases flow and hp is bunk.

1) How would you describe the sound you're referring to (as being off)?
2) Once you get the new X-Pipe installed, how you would describe the difference.
Reason being - the various YouTube demos that I've heard (I know, you can't go by them...) make the Fister solution sound "blatty". Maybe that is only the case at engine startup with the richer fuel mixture.
Perhaps it mellows out a little bit after that.
I would be very interested to get your impression once the center muffler is removed and the X-pipe is in place.
Thanks.

once I get my car back, I will take some video of cold start, then some revs once warmer. Will do it again after the x pipe. I know the iPhone won’t capture everything but best I can do.
The sound being slightly off almost sounds to me like what a slight exhaust leak from the manifold gasket would sound like, without ever hearing what that actually sounds like. It’s why I am really considering changing them out when I have the bumper off, which is also why I was considering changing out the plugs and coils as well. Some have told me not to bother unless I’m having CEL which I’m not. Still torn.

In a previous post in this thread you mentioned that your exhaust system (Gundo hack) sounds off with the center muffler in place. I would be curious to know:

$44.95 - but the shipping added to that may negate the deal as being competitive, I don't know. Possibly may be able to get free shipping given their need to generate sales now...

I know that some feel the Sharkwerks didn't seem to give them an increase in HP or torque but I felt it. It was a nice pop for me. Sound improves too and it's still pretty quiet with sports exhaust switched off. I really recommend it. They'll give you a 10% coupon if you ask. Nice stuff.
Also want to mention our barbers and other folks we may not see. Hairstylists and ladies that do nails don't get unemployment. At least in Cali. My wife's best friend is super upset so we gifted him some green and I told my barber I'd take care of him. And my wife's folks too. I hit the restaurants we normally go to and tipped extra. These people are scared as sh*t. I could see it. Restaurants make money on drinks....there's no liquor sales on to-go orders.
If everyone who can does a little it can possibly save a life. Our friend was in a dark place.
