Fabspeed HFC and resonated x pipe mini review

[Black Gold]

A friend of mine installed this on his car today with the help of Richard from M-world here in the great city of Houston. Big credit goes to Richard, the install went well and everything turned out great.

The car is a 2009 e90 m3 6mt with only an AA green filter for mods. The plan was to install the full Fabspeed setup which was purchased used from another member.

The install was great with minimal fitment issues (always something as expected).

The results are that the car sounds fantastic. The car sounds essentially stock while idling and crusing at any speed. There is a little growl at about 2-3k rpm, but it is not too loud at all (i am very sensitive to overly loud exhausts). When you are on the loud pedal, the car sounds outstanding, screaming to redline. A+ for sound considering the car still has the stock muffler.

The power gains are noticeable in two ways. One, there seems to be a very noticeable bump in low end torque and also feels like max thrust comes in earlier than before. The car also rips to redline more than before, feeling like it has more juice at the top end. Id say the car feels like between 2-3k rpms it has 20+ wtq easy more than stock, and probably at least 15+ wtq more than stock overall. Feels like it has about 15-25whp over stock as well. Very noticeable. As a comparison, the AA filter felt like it added nothing (but still a worthwile mod if you have a dirty oem filter).

Car looks, drives and sounds great. Very pleased with the product, and plan to make no more changes to the exhaust system. Perfect as is.

Nice write up I loved the raspy sound when I paired my Fabspeed xpipe w/OEM mufflers.

If you decide to get an aftermarket muffler I know someone that's selling one

Thanks for the comments, its great. A CEL did get thrown already though on the car, which is disappointing, but expected nonetheless.

We did get some sound clips, but only have the video files and no way to post them

Does it have the O2 extenders?
No check engine light is the main draw to this unit.

nope, no extenders. before googling them, we didnt know much about them or know to try them....

still disappointing that the car threw the codes. definitely cant pass inspection like this

Nice! Thanks for sharing. I am hoping to get just an XPipe for our otherwise stock E90 M3 sometime in the near future.

That's odd that your friend pulled a CEL. Fabspeed advertises that their XPipe with HFC OBDII Compliant and should not pull a CEL.

yea, we sort of knew that this would be a risk from searching the forums, but to have basically driven 30 miles, throw an SES light, clear it, and throw another one in 30 more miles is frustrating.

the previous owner reported no SES light, so it seems that there are many variables involved.

in this case, proper installation is not an issue, the job is very simple

He should ask for the O2 extenders. They basically pull the O2 sensors out of the flow of exhaust a little more. Many have said they work most of the time. You may through a code but it'll clear later.
