If you have the turbo XS with 3 bar you may as well just forget the bottom pipe. i love the company and their products but the 3 bar hits the fan shroud and its just not a good time and the one elbow was marked from rubbing on something. I went back to stock.

 

Its the same way with the Hahn. Either hitting the a/c lines or fan.

 

Damn, how did it do that? Just curious.

 

It basically rubbed through the electrical connector on the AC pump with the MAP sensor plug. Not having a clue I brought it in for warranty ("AC not working") and ended up having to pay for installing a new harness because the damage was caused by aftermarket parts...

 

Yup, I had the same issue except my piping would pop it loose. Also the GMS1 sensors in the Hahn piping just won't work, lol. Ended up breaking a connector off the map sensor trying to make it fit. Still made contact but there was a big crack across the connector. When I got my zzp piping I ordered a new sensor.
