N55 ER Charge Pipe Silicone FMIC Piping Couplers!
There has been some discussion as to the various mounting choices (i.e. silicone or factory C-clip) at the turbo but I have also been asked a few questions about the second connection at the intercooler piping as a few users have posted it coming loose.
The ER charge pipe in particular uses a solid elbow, while some other manufacturers make the elbow out of silicone, making the silicone piece larger. There was some discussion on which is better so I thought I would get ER's take on it... Quote:

** Evolution Ralliart as an example (extreme example), where you have a LONG rubber hose. The short 90 degree hose doesn't have enough surface area to expand and balloon. Also with under 30psi of boost, I would put it on installation errors of loose clamps rather then hardware failures. I personally have been running our charge pipe with silicone couplers and never had a problem with couplers popping off. ** N54 pictured, but we make it for the N55 as well. ** Installed picture on the N55. I'm not trying to argue our product since we don't even use a 90 degree coupler, we use a straight coupler which will never have a problem. I just know from experience with a good high quality coupler, it will not pop off or balloon under boost unless the legs are excessively long. Michael |

I'd still prefer the ETS coupler over my ER coupler for piece of mind. Doesn't matter to me though because I am installing the ER FMIC soon, so I'll be affixing my coupler to a metal lower IC pipe. I can say that my ER coupler DID pop off once and it was secure during the initial installation. It's too small.

I can attest to the ETS couplers not popping off. I took mine to the track the next day after getting it installed and I had 0 issues with about 2+ hours of pure track time.
But my installer did use an air tool to make sure the T Bolt clamps were very secure. |

My best friend used silicone piping everywhere on his WRX (32+psi) and had no ballooning issues. That said, the clamp will work extremely well too. There shouldn't be issues with either of the coupling components if they are installed correctly.
