M3OwnerHtown · 04-22-2010, 11:09 AM

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 had fabspeed before and it was great. replaced with Akra Evo

What is a v-band?

Style of clamp.... Really shouldn't be a bases of your decision

powertrip · 04-22-2010, 07:06 PM

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.

Isn´t the pipe diameter different on both? That alone should make for different power outputs?

GirlsGarage · 04-23-2010, 04:58 PM

I am also planning to get an X pipe and HFC but not realy sure which ones to get!

anybody experienced with FabSpeed ones??!!

schnell325 · 04-23-2010, 05:07 PM

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.

disruptv · 04-25-2010, 08:36 AM

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!
