Fabspeed X-Pipe vs AA X-Pipe

Hey guys,
I'm looking into getting a an X-Pipe and wanted feedback from those who had either X-Pipe's or personnel knowledge and pro's con's between the two?

Fabspeed XPipe with Resonators verse Active Autowerke X-Pipe Gen 2
-Horsepower/Torque gains?
-Loudness/Drone?
-Any CEL?

Thanks!

comparable product.... both should come in right about the same on HP/torque. volume should be the same. AA claims to have new HFC's that don't give a CEL. Fabspeed claims no CEL too, but almost everyone has gotten one at one point or another. I have gotten a CEL twice with my Fabspeed, but it will clear itself after a few hundred miles. I think their price is a bit better than AA

I think you should go AA; I'm a fan of their V-band connection between the HFC's and the x-pipe.

I'll disagree with you on this one. In my experience V-bands leak less than slip-fits like the Fabspeed. Put it this way, Tial is making a GT35R turbo that is held together with V-band clamps; they wouldn't dare do that with a slip-fit due to the possibility of boost leak.

no leaks on my Fabspeed and I've had it installed for almost a year. with about 4-5K miles on it.

Isnīt the pipe diameter different on both? That alone should make for different power outputs?

I'm quite happy with the fit and finish of my catless AA x-pipe.

While your at the x-pipe......why not add a short shift kit if you think one would benefit you.

this will have to do with your choice of muffler.

I went with Encore, good HFC's. Only had one CEL, reset it and no problems. Good sound, excelleration. But not a fan of the clamp set up at the headers. had to use some exhaust seal to stop the air leaks. Fabspeed I think from what I've seen has a better fitting set up at the headers. Good luck!
